Answer: Option (B) is the correct answer.
Explanation:
A nuclear reaction is a reaction in which nucleus of an atom either splits or joins with the nucleus of another atom.
In a nuclear reaction, there will be nuclear fission and nuclear fusion reactions. During these reactions, radiations are emitted due to the radioactive decay of the nucleus of atoms.
These radiations are harmful in nature.
Thus, we can conclude that exposure to radiation is the potential danger from an accident at a nuclear power plant.
