The correct answer is (c), hydro-electricity.
Coal is a non-renewable resource that produces greenhouse gases when burned. Mineral oil and gas are also non-renewable resources that produce greenhouse gases when burned. Atomic energy is a non-renewable resource that produces radioactive waste. Hydro-electricity is a renewable resource that does not produce greenhouse gases or radioactive waste.
Coal is a fossil fuel that is formed from the remains of ancient plants and animals. It is a non-renewable resource, which means that it cannot be replaced once it is used up. Coal is used to generate electricity, produce steel, and make other products. When coal is burned, it releases greenhouse gases into the atmosphere, which contribute to climate change.
Mineral oil and gas are also fossil fuels that are formed from the remains of ancient plants and animals. They are non-renewable resources, which means that they cannot be replaced once they are used up. Mineral oil and gas are used to generate electricity, power vehicles, and make other products. When mineral oil and gas are burned, they release greenhouse gases into the atmosphere, which contribute to climate change.
Atomic energy is a form of energy that is released when atoms are split apart. It is a non-renewable resource, which means that it cannot be replaced once it is used up. Atomic energy is used to generate electricity and produce nuclear weapons. When atomic energy is used, it produces radioactive waste, which is a dangerous substance that can pollute the environment.
Hydro-electricity is a form of energy that is generated by the flow of water. It is a renewable resource, which means that it can be replaced over time. Hydro-electricity is used to generate electricity and produce hydroelectric dams. When hydro-electricity is used, it does not produce greenhouse gases or radioactive waste.
In conclusion, the best source of generating electricity in India from the viewpoint of sustainable development is hydro-electricity.
