It produces much more energy than nuclear fission
The process is used for making nuclear bomb.
Electricity production through this process is commercially less viable than nuclear fission.
It is the source of energy in the stars.

Answer 1

The correct answer is option 2 i.e., The process is used for making nuclear bombKey Points

A nuclear bomb uses either uranium or plutonium and relies on fission, a nuclear reaction in which a nucleus or an atom breaks into two pieces.
The by-products of nuclear fission include free neutrons, photons usually in the form of gamma rays, and other atomic fragments such as beta particles and alpha particles.
Nuclear fission produces energy for nuclear power and drives atomic weapon explosions.
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
An example of nuclear fusion is the process of four hydrogens coming together to form helium.
A hydrogen bomb is based on the principle of uncontrollable nuclear fusion.
