Hint:

Answer 1

The Correct Option is D

Concept: Lignite, often referred to as "brown coal," is a lower grade of coal with high moisture content. In India, the largest deposits of lignite are found in the southern state of Tamil Nadu.

Step 1: Identifying the Neyveli Region.
Neyveli is a prominent industrial town in Tamil Nadu, managed by the NLC India Limited (formerly Neyveli Lignite Corporation). It is the most significant source of lignite in the country, powering major thermal power stations.

Step 2: Locating the District.
Geographically, the Neyveli lignite mines are situated within the Cuddalore district of Tamil Nadu. The lignite here occurs in the tertiary rocks of the coastal plain.

Step 3: Analyzing other options.

• West Singhbhum: Located in Jharkhand, famous for iron ore (Noamundi, Gua).
• Karimnagar: Located in Telangana, known for coal (Godavari Valley) but primarily bituminous.
• Sibsagar: Located in Assam, famous for oil fields like Lakwa and Rudrasagar.
