Single replacement reactions

They are also known as single displacement reactions.

They are reactions in which one element takes the place of another in a compound. That is, one element replaces another in a compound.

Looking at all the reactions from A - D, one can see that the only reaction that exemplifies a single replacement reaction is D.

Here, Zn replaced H in HCl.
