Which sugar is a monosaccharide with five carbons according to the material?

Explanation:
Five-carbon sugars are pentoses. In monosaccharides, ribose has five carbons, making it a pentose, and it typically exists as an aldopentose. The other sugars listed—glucose, fructose, and galactose—each have six carbons, so they are hexoses. So ribose is the monosaccharide with five carbons.
