The correct answer is D.

The types of atoms present change in nuclear reactions but do not change in chemical reactions.

When nucleus reaction takes place in atom nucleus the electrons which are in the atom are much responsible for chemical reactions. Chemical reaction it involves the loss, gain, transfer, and sharing of electrons and there is no place for nucleus. Nuclear reaction needs decomposition of nucleus and there is no electrons. If nucleus decomposes it may lead to change to another atom reason being loss of protons or neutrons. Nuclear reaction neutrons and protons react inside whereas chemical reaction electrons they take reaction outside of the nucleus.
