Solution

The correct option is D. 100 degrees.
Since the angle of incidence is equal to the angle of reflection, the angle of incidence is also 50 degrees. The angle between the incident ray and reflected ray is the sum of the angle of incidence and the angle of reflection which is (50+50) degrees i.e. 100 degrees.
