Answer:

The correct answer is c) Nuclear energy.

Explanation:

• Biomass energy is the energy derived from living organisms, alive or dead. The biomass energy is obtained from a carbon source.

1. Wood is a renewable source of energy. The major constituent of wood is carbon. The energy which gets stored in the wood of the tree is obtained by the process photosynthesis.
2. Gobar gas is a biofuel which is produced by the decomposition of organic wastes. It is composed of mainly methane, carbon dioxide and carbon monoxide.
3. Nuclear energy is obtained from radioactive substances like uranium, radium, etc, which can undergo nuclear fission and fusion reactions.
4. Coal is produced by the action of excessive heat and pressure on the buried masses of dead plants and animals that lived several thousand years ago.
