Which of the following is a reducing sugar that is a disaccharide?

Explanation:
Reducing sugars are those that can open to reveal a free aldehyde or ketone at an anomeric carbon, allowing them to act as a reducing agent. Maltose is two glucose units linked by an α(1→4) bond; in this linkage one anomeric carbon is involved in the bond, while the other anomeric carbon on the second glucose remains free. That free anomeric carbon can open to form an aldehyde, so maltose behaves as a reducing sugar. The other options don’t fit because starch and cellulose are polysaccharides, not disaccharides, and glucose is a monosaccharide.
