Which molecule has the sugar deoxyribose?

Explanation:
The sugar deoxyribose is the five-carbon sugar found in DNA. It lacks an oxygen at the 2' position (hence the name "deoxy"), whereas RNA uses ribose, which has a hydroxyl group at the 2' carbon. Because DNA’s nucleotides are built with deoxyribose in the backbone, the molecule that has deoxyribose is DNA. This difference in sugar also helps explain why DNA is generally more chemically stable than RNA.
