D-Glucose, D-mannose and D-fructose are separately reduced with $NaBH X_{4}$ . The total number of different alditols obtained from the three reactions is

A1
B2
C3
D4

Answer: B

Glucose gives D-glucitol and mannose gives D-mannitol. Fructose gives both. So only two distinct alditols are formed in all.
