Answer: b) Chota Nagpur Plateau
Explanation
- Chota Nagpur Plateau: Located primarily in Jharkhand (and parts of Odisha, West Bengal, Bihar, and Chhattisgarh), the Chota Nagpur Plateau is known as the “Storehouse of Minerals” or the “Ruhr of India” (after Germany’s mineral-rich Ruhr region).
- Mineral Wealth: It accounts for a massive portion of India’s mineral reserves, including coal, iron ore, mica, bauxite, copper, limestone, and manganese. Famous mining hubs like Jharia, Bokaro (coal), Singhbhum (iron ore/copper), and Kodarma (mica) are located here.
Overview of Other Options
- a) Deccan Plateau: Famous for its Deccan Traps (black cotton soil / regur), rich in iron and magnesium basalt rocks, and major hydroelectric potential.
- c) Malwa Plateau: A volcanic plateau in Madhya Pradesh and Rajasthan, known for its fertile black soil and agriculture (cotton, soybean) rather than mineral deposits.
- d) Ladakh Plateau: A high-altitude cold desert plateau in northern India, featuring geothermal energy reserves and salt lakes, but not a primary mineral industrial hub.
