In a Nucleotide, we find which other biomolecule (s) making up a piece of the nucleotide itself?

If these are the choices:

A. No other biomolecules are present

B. Protein

C. Lipid

D. Carbohydrate

My answer is D. Carbohydrate.

A nucleotide has three parts. These parts are 1) nucleobase aka nitrogenous base, 2) a five-carbon sugar or pentose sugar (either ribose or 2-deoxyribose), and 3) one or more phosphate groups.

D. Carbohydrate is under the 2) pentose sugar part of the nucleotide.
