Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In a prism with equal base angles, the deviation is minimum therefore the refracted ray becomes parallel to the base of the prism. As in the case of minimum deviation, angle of incidence is equal to the angle of emergence.
