Solution

The correct option is C Assertion is correct but Reason is incorrect
Optical isomers are named like this because of their effect on plane polarized light.

Optical isomers get their name because the plane of plane-polarized light that is passed through a sample of a pure enantiomer is rotated. The plane is rotated in the opposite direction but with the same magnitude when plane-polarized light is passed through a pure sample containing the other enantiomer of a pair.

(+)-form of isomer rotates the plane polarised light in the clockwise direction and (-)-form of isomer rotates the plane polarised light in the anticlockwise direction.

Option C is correct.
