(C) Given: Angle of prism,$A = 30^o$,Angle of incidence,$i = 60^o$,Angle of deviation,$\delta = 30^o$.Using the prism formula for deviation: $\delta = i + e - A$.Substituting the values: $30^o = 60^o + e - 30^o$.Solving for the angle of emergence $e$: $e = 30^o + 30^o - 60^o = 0^o$.Since the angle of emergence $e = 0^o$,the emergent ray is normal (perpendicular) to the second face of the prism.Therefore,the angle made by the emergent ray with the second face of the prism is $90^o$.
