The commercial power generation is done using the nuclear fission reaction.
Answer: option B
Explanation:
The nuclear fission reaction is the reaction in the nucleus where the nucleus is divided into smaller parts. It is apparent from the name itself as it’s a destructive reaction where the nucleus splits.
This splitting of the nucleus occurs as a result of the heavy bombardment done over the atom through which the nucleus splits. The splitting is done into many parts of a smaller size.
