Type of sugar in RNA?

Explanation:
RNA uses ribose as its five-carbon sugar. Ribose is an aldopentose with a hydroxyl group on the 2' carbon, which distinguishes it from deoxyribose (the sugar in DNA) that lacks that 2' OH. That 2'-hydroxyl makes RNA more chemically reactive and less stable, helping RNA form diverse single-stranded structures and even catalytic roles. The other sugars listed aren’t used in the nucleic acid backbone: glucose and fructose are metabolic hexoses, not components of RNA, and deoxyribose is the sugar of DNA, not RNA.
