The correct answer is: A) Coal
Telangana has significant reserves of coal. The state is home to the Singareni Collieries Company Limited (SCCL), which is one of the largest coal mining companies in India. The SCCL has coal reserves of over 8 billion tonnes, and it produces over 60 million tonnes of coal per year.
Coal is a fossil fuel that is used to generate electricity, produce steel, and make other products. It is a non-renewable resource, which means that it cannot be replaced once it is used up.
The use of coal has a number of environmental impacts, including air pollution, water pollution, and greenhouse gas emissions. However, coal is still a major source of energy in India, and it is likely to remain so for the foreseeable future.
The other options are incorrect because:
- Petroleum is a fossil fuel that is used to produce gasoline, diesel, and other fuels. Telangana does not have significant reserves of petroleum.
- Natural gas is a fossil fuel that is used to generate electricity, produce heat, and make other products. Telangana does not have significant reserves of natural gas.
- Bauxite is a mineral that is used to produce aluminum. Telangana does not have significant reserves of bauxite.
