- DFructose
Correct answer
C. Lactose
Step-by-step solution
Lactose or milk sugar (carbohydrate) is reducing sugar formed through (\beta-1 \rightarrow 4) condensation between galactose and glucose. Lactose does not occur in nature except as a product of the mammary gland. It is highest in human milk as compared to that of cow, buffalo and goat. Lactose is a product of glucose, fructose and galactose.
