Solution

The correct option is C D-fructose
Sucrose also called invert sugar is a disaccharide which means it is made up of two monosaccharides i.e. D-glucose and D-fructose. It is a non-reducing sugar because reducing ends of both glucose and fructose participate in bond formation. The enzyme that hydrolysis sucrose is invertase.
Glucose and galactose combine to form lactose.
So, the correct option is 'D-fructose'.
