The correct answer is: D) All of the above.
The Mines and Minerals (Development and Regulation) Act, 1957 (MMDRA) is a central act that regulates the mining sector in India. The Act provides for the grant of prospecting licenses, mining leases, and other mineral concessions. It also regulates the environmental aspects of mining, such as the prevention of pollution and the rehabilitation of mined areas.
The Telangana State Mineral Policy, 2015 is a state policy that provides for the development and regulation of the mining sector in Telangana. The Policy aims to promote sustainable mining and to ensure that the benefits of mining accrue to the people of Telangana.
The National Mineral Policy, 2010 is a national policy that provides for the development and regulation of the mining sector in India. The Policy aims to promote sustainable mining and to ensure that the benefits of mining accrue to the people of India.
All three of these policies play a role in regulating the mining sector in Telangana. The MMDRA is the overarching law, while the Telangana State Mineral Policy and the National Mineral Policy provide more specific guidance on how the MMDRA should be implemented in Telangana.
