D. nucleic acid.

Answer

B

Explanation

Cytosine (C) is a pyrimidine i.e., a nitrogenous base. A combination of a nitrogenous base (purine pr pyrimidine) with a pentose sugar is known as nucleside. Thus, the combination of cytosine with ribose sugar results in the formation of a nucleoside called as cytidine. similarly, the combination of cytosine with dexyribose sugar is called as deoxycytidine.
