Ooty (Udhagamandalam), the famous hill station is located in the Nilgiris.

Option (d) is incorrect: The Shevaroy Hills are a smaller mountain range located in the Eastern Ghats of Tamil Nadu. They are known for their coffee plantations and the hill station of Yercaud. As part of the Eastern Ghats, the Shevaroy Hills are geographically separate from the meeting point of the Eastern and Western Ghats, which is defined by the Nilgiri Hills.

Explanation

Pair (1) is incorrectly matched: The Chambal River is a major tributary of the Yamuna River, a significant river in North India. The Narmada River, on the other hand, flows westward and is independent of the Yamuna and Chambal river systems. These two rivers are geographically separated and do not share a tributary-main river relationship.

Pair (2) is incorrectly matched: The Sone River is a tributary of the Ganga River, not the Yamuna. It originates in the Amarkantak Plateau (Madhya Pradesh) and joins the Ganga near Patna.

Pair (3) is correctly matched: Manas originates in the Himalayas in Bhutan and flows through Assam. It joins the Brahmaputra near Jogighopa. It is known for its rich biodiversity and is part of the Manas National Park, a UNESCO World Heritage Site.

Explanation

Explanation

Coal mining plays a crucial role in India’s energy sector, and the Namchik-Namphuk coalfields are an important part of India’s northeastern coal reserves.

Option (a) is correct: Arunachal Pradesh: Arunachal Pradesh’s primary coal resource is concentrated in the Namchik-Namphuk coalfields located in the Changlang district. These are the most significant coal-bearing areas in the state, though they are relatively small compared to major coalfields elsewhere in India. The coal found here is generally of tertiary age.

Option (b), (c) and (d) are incorrect:

Meghalaya possesses coal deposits, primarily in the Garo Hills region, which includes areas like Nangalbibra, Siju, and others. The coal here is typically sub-bituminous. It’s important to note that much of the coal mining in Meghalaya is done through small-scale, often unregulated operations (rat-hole mining) which has raised environmental concerns. Manipur has limited coal resources, and no significant, named coalfields are widely recognized. Coal occurrences are scattered and generally not considered commercially viable. Exploration has been carried out in areas like the Ukhrul district, but large-scale mining operations are not a feature of the state. Mizoram has no significant coalfields within the state. Coal occurrences are scattered and not considered economically significant. The geological formations in Mizoram are not conducive to the formation of large, commercially viable coal deposits.
