Solution

The correct option is D Glucose + Fructose
Answer:- (D) Glucose + Fructose
Sucrose on hydrolysis gives an equimolar mixture of D-(+)-glucose and D-(-)-fructose. These two monosaccharides are held together by a glycosidic linkage between $C - 1$ of $α$ -glucose and $C - 2$ of $β$ -fructose.
