Deoxyribose in DNA nucleotides belongs to this family of biologically important molecules:

This question tests understanding of how biomolecules are classified by chemical nature. Deoxyribose is a sugar, so it belongs to carbohydrates. It’s the five-carbon sugar component that forms the backbone of DNA nucleotides, linking with phosphate groups and bases. Carbohydrates include sugars like glucose, ribose, and deoxyribose, which distinguishes them from proteins (made of amino acids), lipids (fats and related molecules), and nucleic acids (DNA and RNA themselves as polymers). The term deoxyribose also highlights that it’s a sugar missing one oxygen atom compared with ribose, reinforcing its place in the carbohydrate family.
