The correct answer is:
For a prism, as the angle of incidence of light increases the angular deviation of light decreases upto a certain value and after a particular value of angle of incidence, the angular deviation starts to increase.
The correct graph that represents the variation of angular deviation with angle of incidence is shown below.
