Explanation:
RNA or ribonucleic acid is the nucleic acid which was formed in the primordial time. The RNA molecule acts as an enzyme called ribozyme and also acts as the genetic material of a few viruses.
The RNA is composed of nucleotide monomer where each nucleotide is made of a ribose sugar, a phosphate group and the nitrogenous base adenine, uracil, cytosine and guanine.
Thus, option-D is the correct answer.
I think the answer is D, because the DNA wraps around proteins called histones to form chromatid.
