D
C5H10O5
Explanation: 

Detailed explanation-1: -The molecular formula C5H10O4 (molar mass: 134.13 g/mol, exact mass: 134.0579 u) may refer to: Deoxyribose, or 2-Deoxyribose. L-Deoxyribose. Monoacetylglycerol.

Detailed explanation-2: -Deoxyribose | C5H10O4 | ChemSpider.

Detailed explanation-3: -Deoxyribose is also known more precisely as 2-deoxyribose and is a component of DNA. Any molecule that ends in ‘ose’ is considered a sugar. The chemical formula for deoxyribose is C5 H10 O4.

Detailed explanation-4: -5-deoxy-D-ribose is a deoxypentose that is aldehydo-D-ribose in which the hydroxy group at position 5 is substituted by a hydrogen. It is functionally related to a D-ribose. 5’-Deoxyribose is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).
