The statement is true only for chemical reactions is the atoms of the reactants are reorganized.
When a change or transformation occurs in a substance in which the constitution of matter is altered, we say that this is a chemical phenomenon, or rather, that a chemical reaction has occurred.
In the case of chemical reactions we have that a reorganization of its molecules of the atoms will occur so that they give result to another substance.
Only alternative B is correct because we can only mess with the reorganization of an atom, never the nucleus.
