Solution

The correct options are
A It is sucrose.
D Due to absence of hemi-acetal linkage, it can't show mutarotation.
Since the reducing groups of glucose and fructose are involved in glycosidic bond formation, sucrose is a reducing sugar. Sucrosees do not show mutarotation because the glycosidic bond is between the anomeric carbon of glucose and fructose.
6 membered ring is glucose while 5 membered ring is fructose.
