Correct option is B
The correct answer is Iron-ore.
· The Gua mines, located in the West Singhbhum district of Jharkhand, are rich in iron ore reserves.
· These mines are among the prominent iron ore mining sites in India, managed primarily by the Steel Authority of India Limited (SAIL).
Details:
- Iron-ore: The Gua mines produce high-grade iron ore, which is a key raw material for steel production. The ore extracted from these mines is supplied to steel plants across India.
- Other Minerals: While Jharkhand is known for minerals like coal, bauxite, and zinc, these are found in different regions, not associated with the Gua mines.
Clarifications for Other Options:
- Zinc: Found in states like Rajasthan but not associated with the Gua mines.
- Bauxite: Found in Lohardaga and other parts of Jharkhand but not in the Gua mines.
- Coal: Jharkhand has significant coal reserves (e.g., Dhanbad), but coal is not mined in Gua.
