The correct answer is: 23%.
Chhattisgarh is the largest producer of iron ore in India, accounting for about 23% of the country’s total production. The state has rich deposits of iron ore, which are found in the Bailadila, Dalli Rajhara, and Korba iron ore belts. The Bailadila iron ore belt is the largest in the state, and it is estimated to contain about 2.5 billion tonnes of iron ore reserves. The Dalli Rajhara iron ore belt is the second largest in the state, and it is estimated to contain about 1.5 billion tonnes of iron ore reserves. The Korba iron ore belt is the third largest in the state, and it is estimated to contain about 1 billion tonnes of iron ore reserves.
The iron ore produced in Chhattisgarh is used by steel mills in India and abroad. The state’s iron ore industry is a major contributor to the state’s economy, and it employs thousands of people.
The other options are incorrect because they do not represent the correct percentage of iron ore deposits in Chhattisgarh.
