The correct answer is option A (1 and 3 only).
Explanation:
Statement 1 is correct. The Mines and Minerals (Development and Regulation) Act, 1957, which regulates the mining sector in India, defines minor minerals as minerals other than major minerals.
Statement 2 is not entirely correct. Under the Constitution of India, regulation of mines and mineral development is a state subject. Thus, state governments have the power to grant mining leases of minor minerals as well as to frame rules related to their grant. However, the Central Government has the power to make rules for the whole country in respect of any matter relating to minor minerals.
Statement 3 is correct. State governments have the power to frame rules to prevent illegal mining of minor minerals. For example, several states have enacted rules to regulate the transportation of sand and other minor minerals to curb illegal mining and transportation.
