Solution

The correct option is C rearrangement
Dalton's atomic theory states that atoms can neither be created nor be destroyed. The existing atoms get rearranged during a chemical reaction.

Consider the following reaction:
Zn(s)+2HCl(aq)ZnCl2(aq)+H2(g)
Here, the same number of atoms of zinc, hydrogen and chlorine are present on the reactant side and the product side.
Hence, no creation or destruction of atoms occur; they only get rearranged to form new compounds.
