The reaction is an example of: $\mathrm{Zn}+2\mathrm{HCl}\to {\mathrm{ZnCl}}_2+{\mathrm{H}}_2\uparrow$ 

A chemical reaction in which one element of the compound is replaced by a similar type of element due to its higher reactivity, is known as a displacement reaction.

Here in the given reaction zinc displaces hydrogen from the hydrochloric acid in this situation. This is also an instance of a displacement reaction.

Hence option (C) is correct.
