Glucose and mannose are:

A anomers.
B epimers.
C enantiomers.
D non superimposable mirror images.
Ans. B Glucose and mannose are not anomers, nor are they are mirror images. So Choices A and C are ruled out. Choice D is not true. In fact, they are epimers. Epimers are isomeric sugars that differ in their configurations only at one of their stereogenic centers.
