In a prism of angle A and refractive index µ, if the maximum deviation occurs then which is not possible
(a) The angle of incidence is 90°
(b) The angle of incidence is sin-1 [√(µ2 - 1)(sin A) - cos A
(c) The angle of emergence is sin-1 [µsin(A - θC)]
(d) The angle of emergence is equal to the angle of incidence.
