Correct Answer
B They rotate the plane of polarized light by differing amounts and in opposite directions.
C They rotate the plane of polarized light by differing amounts and in the same direction.
D They have different melting points.
Correct Answer

Option A is the correct answer.

Detailed Explanation

Enantiomers rotate plane-polarized light by the same magnitude but in opposite directions (one clockwise, one counterclockwise). This is the defining property of enantiomers.

Hint

How do enantiomers differ in their optical rotation?
