Key concepts:

Non-reducing sugar: A sugar that does NOT reduce Fehling's/Tollens' reagent. This happens when the anomeric –OH of ALL monosaccharide units is involved in the glycosidic linkage (no free –CHO or –OH at anomeric carbon).

Reducing monosaccharides: Glucose and fructose both have free anomeric –OH after hydrolysis and are reducing sugars.

Evaluating options:
- Fructose: monosaccharide (cannot hydrolyse further) — reducing sugar itself
- Galactose: monosaccharide — reducing sugar
- G
