A typical nucleic acid has 3 components which include:
A purine or pyrimidine nitrogenous base
A phosphate group
A 5-carbon sugar
The purine base includes adenine and guanine while the pyrimidine base includes thymine/uracil and cytosine. The 5-carbon sugar could be ribose or deoxyribose depending on if the nucleic acid is ribonucleic or deoxyribonucleic acid.
<em>The only macromolecule that contains the 3 components of the options A to D is the nucleic acid. Hence, the correct option is </em><em>D.</em>
