Solution

The correct option is D It cannot show mutarotation
a) Since in this disaccharide, glycosidic bonds are not between the two anomeric carbon hence it can reduce Tollen's reagent.
b) For the above reason it can also reduce Fehling solution.
c) Both monosaccharides of it are D-type.
d) Since one anomeric OH is free so it will show mutarotation.
