A

(-) Fructose

B

(+) Sucrose

C

(+) Lactose

D

(+) Maltose

Text Solution

Verified by Experts

The correct Answer is:
B
Only monosaccharides , i.e., (-) -fructose , and reducing disaccharides , i.e., (+) -lactose and `(+)` - maltose , show mutarotation, Since `(+)`- sucrose is a non -reducing sugar , it does not show mutarotation. Thus , option (b) is correct.
