Answer 2

Examples of epimers are glucose and lactose, and mannose and glucose also so option(D) is the correct one.

• lactose is an aldohexose and a C-4 epimer of glucose. A galactose molecule correlated with a glucose molecule constructs a lactose molecule.
• Glucose and mannose act as C2 epimers.

• Epimer in stereochemistry determines one of a pair of stereoisomers. At the stereogenic centre, two isomers existing in the molecules differ, while the rest persists similar. A molecule may comprise various stereocenters directing to numerous stereocenters.
• Stereoisomers are isomeric molecules that contain a similar establishment and molecular formula, but they differ in the three-dimensional orientations of their atoms in space.
