The correct answer is (b) Chhattisgarh.
Chhattisgarh is the leading producer of tin in India. It accounts for about 80% of the country’s tin production. The state has large reserves of tin ore, which is mined in the Korba district. The tin ore is then processed at a smelter in the same district.
Andhra Pradesh, Jharkhand, and Orissa are also producers of tin, but they produce much less than Chhattisgarh.
Andhra Pradesh has small reserves of tin ore, which is mined in the Visakhapatnam district. The tin ore is then processed at a smelter in the same district.
Jharkhand has small reserves of tin ore, which is mined in the Ranchi district. The tin ore is then processed at a smelter in the same district.
Orissa has small reserves of tin ore, which is mined in the Keonjhar district. The tin ore is then processed at a smelter in the same district.
