Solution

The correct option is C

Incident ray, reflected ray and the normal all lie in the same plane.


Laws of reflection holds true for all kinds of reflecting surface. Since the above surface is irregular, hence the normal at different points will be in different directions but the laws of reflection will be applicable at each of these minute surfaces where reflection is happening.
