    deoxyribose is the correct option.

    Explanation:

    The sugar present in DNA is called deoxyribose.

    Deoxyribose is a pentose type of sugar, it is made up of ten hydrogen atom and the oxygen atom is four.

    which plays a major role in DNA formation, it is a building block of the DNA.

    Deoxyribose sugar makes the DNA stable as compared to RNA because it has one oxygen less containing hydroxyl group.

    Thus DNA contains deoxyribose sugar molecule.
