Verified by Experts

The correct Answer is:
A, B
Non reducing sugar-carbohydrates in which free carbonyl group are not present are known as non reducing sugar.
In lactose and maltose free `-underset(O)underset(||)(C)-` group present that means it is a reducing sugar.
Sucrose does not have free `-underset(O)underset(||)(C)-` group so these are known as non-reducing sugar.
