Correct Answer:
Option A - When a ray of light is incident passing through the centre of curvature of concave mirror or appear to pass through the centre of curvature of convex mirror, then after reflection it returns on the same path again and in the same medium. Therefore the angle between the incident stay and the reflected ray will be 0⁰.
