Assertion : Any ray of light suffers a deviation of `(180^@-2i)` after one reflection.
Reason : For normal incidence of light deviation is zero.

A

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.
