Explanation

National Income refers to the total monetary value of all final goods and services produced by a country’s residents within a specific period, usually a year.

Option (b) is correct: NNP at factor cost is the total income earned by factors of production owned by a country’s residents. This is also called National Income (NI). It excludes indirect taxes (like GST) and adds subsidies granted by the government from NNP at market price. NNP(FC) =NNP(MP) -(Indirect Taxes)+(Subsidies) Options (a), (c) and (d) are incorrect:

NNP at market price is the total market value of all final goods and services produced by the residents of a country (both within and outside the domestic boundary) after adjusting for depreciation. This measure reflects the monetary worth of the economy’s output, including taxes and subsidies. NNP(MP)=GNP(MP)-Depreciation Net Domestic Product (NDP) at Market Price is the net value of all final goods and services produced within the domestic territory of a country after accounting for depreciation. This measure focuses on the domestic economy only (excludes foreign factor earnings). It includes indirect taxes and excludes subsidies. NDP(MP)=GDP(MP)-Depreciation Net Domestic Product (NDP) at Factor Cost is the total factor earnings from goods and services produced within a country’s borders. NDP at factor cost focuses solely on production within domestic boundaries and reflects the true earnings of factors without tax distortions. NDP(FC)=NDP(MP)-(Indirect Taxes)+ (Subsidies)

Explanation

A is matched with 4: Dr. C. Rangarajan headed the Disinvestment Commission in the 1990s, which was tasked with recommending strategies for the disinvestment of shares in Public Sector Enterprises (PSEs) to improve efficiency and reduce the fiscal burden on the government. B is matched with 2: The Omkar Goswami Committee was formed to examine the issue of industrial sickness and suggest measures for the revival of sick industries. It focused on identifying the causes of industrial sickness and recommending policy interventions. C is matched with 1: Dr. Raja Chelliah chaired the Tax Re-forms Committee in the early 1990s, which laid the foundation for India’s tax reforms. The committee recommended simplifying the tax structure, broadening the tax base, and reducing tax rates to promote economic growth. D is matched with 3: The R.N. Malhotra Committee was constituted in 1993 to recommend reforms in the insurance sector. Its recommendations led to the opening up of the insurance sector to private players and the establishment of the Insurance Regulatory and Development Authority (IRDA).

Explanation

As of the period around 1997, India’s gross domestic savings rate was estimated to be in the range of 20 to 25 percent of GDP. The savings rate has been an important indicator of economic health, influencing investment capacity and overall growth potential.

Explanation

The 1996 WTO Ministerial Conference in Singapore marked a significant milestone in Commerce in Information Technology with the adoption of the Information Technology Agreement (ITA). This agreement, signed by multiple WTO members, aimed to eliminate tariffs on IT products like computers, semiconductors, and telecom equipment, fostering global trade. By reducing trade barriers, the ITA became a key achievement for the WTO, enhancing the technology sector’s integration into the global economy.

Explanation

The Himachal Pradesh Maintenance of Parents and Senior Citizens Act, 1996 was enacted to ensure that children provide financial and physical support to their elderly parents, particularly those who are unable to support themselves.

Explanation

Indian Standard Time (IST) is UTC +5:30 hours, based on the longitude 82°30’ E. The International Date Line (IDL) is at approximately 180° longitude. The difference in longitude between the IDL (180°) and the IST meridian (82°30’ E) is 97°30’ (180° - 82°30’). Time difference calculation: 15° of longitude corresponds to 1 hour of time difference. 97°30’ corresponds to 6 hours and 30 minutes (97.5° × 15° = 6.5 hours). Normal Earth Rotation (West to East):

When it is 12:00 noon at the IDL, it would be 05:30 AM (IST) (because IST is ahead of IDL by 6 hours 30 minutes). Reversed Rotation (East to West):

If the Earth rotates in the opposite direction, the time difference reverses. Instead of being ahead, IST will lag behind the IDL by 6 hours and 30 minutes. When it is 12:00 noon at the IDL, it will be 6:30 PM (18:30 IST).

Explanation

Option (d) is correct: The description refers to an extensive archipelago stretching from Aceh, a province on the northern tip of Sumatra Island in Indonesia, to the Torres Strait, which lies between Australia and Papua, near eastern Indonesia. The distance of about 5,000 miles and the mention of 14,000 islands align with Indonesia, the world’s largest archipe-lagic state, comprising over 17,000 islands. Major islands in this vast archipelago include Sumatra, Java, Borneo (Kalimantan), Su-lawesi, and New Guinea, which is shared with Papua New Guinea. Options (a), (b) and (c) are incorrect:

West Indies: The West Indies, an archipelago in the Caribbean Sea, consists of many islands, cays, and reefs. However, it is much smaller than Indonesia, with fewer islands and shorter distances from north to south. The islands also vary in size but are not as large as Indonesia’s biggest islands. Therefore, the West Indies do not match the description’s focus on vast distances and large island sizes. Japan: Japan, an East Asian archipelago, has a smaller land area and fewer islands than Indonesia. Its north-to-south span is much shorter than 5,000 miles, and its islands, though varied in size, do not include some of the world’s largest. Hence, Japan does not match the description as accurately as Indonesia. Philippines: The Philippines, an archipelago in Southeast Asia, has thousands of islands. However, it is smaller than Indonesia, with shorter distances between its northernmost and southernmost islands. While the Philippines have many islands, they lack the vast size and variety described, especially islands comparable to the world’s largest. Therefore, the Philippines do not match the description as closely as Indonesia.

Explanation

The pituitary gland, often termed the "master gland,” regulates various endocrine glands through its tropic hormones. The parathyroid gland regulates calcium and phosphate balance in the body via parathyroid hormone (PTH) and its activity is independent of pituitary gland control. It is self-regulating, depending directly on calcium levels in the blood. Options (a), (b), and (c) are incorrect: The thyroid, gonads, and adrenal glands are regulated by pituitary tropic hormones such as TSH (thyroid-stimulating hormone), LH/FSH (for gonads), and ACTH (adrenocorticotropic hormone) for the adrenal glands. These glands depend on the pituitary to regulate the production of key hormones that control metabolism, growth, and stress responses.

Explanation

Oxygen transportation in the human body is essential for cellular respiration, which generates energy in the form of ATPs. This process ensures oxygen is delivered to tissues and carbon dioxide is removed efficiently. Oxygen enters the body through the lungs (2), binds to hemoglobin in the blood (1), and is transported to the tissues (3) where it is utilized for energy production. This sequence reflects the physiological process of oxygen transport.

Explanation

Option (b) is correct: The corpus luteum is a temporary endocrine structure found in the ovary formed after ovulation. It produces progesterone, which is critical for maintaining the uterine lining and supporting pregnancy in the early stages. Options (a), (c), and (d) are incorrect: The corpus luteum is specific to the ovary and is unrelated to the brain, pancreas, or spleen.
