Answer 1

CONCEPT:

Bio-mass energy:

Bio-mass is the energy source that is received from animal wastes and plant materials.
For example, cow-dung, various plant materials like the residue after harvesting the crops, vegetable waste, and sewage are decomposed in the absence of oxygen to give biogas.

EXPLANATION:

Atomic energy is not a form of biomass energy.
Biomass energy is the energy obtained from organic fuels.
Coal is a fossil that is formed by dead plants and its formation takes millions of years.
Wood is obtained from trees of forest which are organic.
From the above, it is clear that wood, gobar-gas, and cow-dung are an example of biomass energy sources. Therefore option 1, 2, and 4 is correct.
On the other hand, nuclear energy is obtained from nuclear fusion and fission. Therefore option 3 is incorrect.
So, the correct option is atomic energy.
