You are analyzing the carbohydrate content of three samples: sample A yields glucose+fructose when hydrolyzed, sample B yields glucose+galactose, and sample C yields two glucose molecules. Match each sample to its likely disaccharide identity.

• A. A = lactose, B = sucrose, C = cellulose.
• B. A = starch, B = glycogen, C = sucrose.
• C. A = sucrose, B = lactose, C = maltose.
• D. A = maltose, B = sucrose, C = lactose.

Answer: (C)
