Answer: Option (C) is the correct answer.
Explanation:
When two nuclei and a subatomic particle like proton, neutron or high energy electron collide with each other then it results in the formation of two or more different nuclides.
For example, [tex]^{6}_{3}Li + ^{2}_{1}H \rightarrow 2^{4}_{2}He[/tex]
Whereas in an electrochemical, thermochemical and chemical reaction there occurs change in number of electrons and not in number of protons or neutrons.
Thus, we can conclude that a change in the number of protons or neutrons occurs in nuclear reaction type of reaction.
