    The correct answer will be option-C.

    Explanation:

    The Nucleic acids present in the cells are of two types: Ribonucleic acid (RNA) and the Deoxyribose nucleic acid (DNA).

    These nucleic acids show distinctive differences in their structure like:

    1. Sugar: The sugar in DNA lacks oxygen group at the 2' C which is present in the RNA as OH group is present.

    2. Nitrogenous bases: The nitrogenous base in the DNA are adenine, guanine, cytosine and thymine whereas RNA lacks thymine and have uracil.

    The main difference is the structure if sugar on the basis o which these nucleic acids have been named. Thus, Option-C is the correct answer.
