Solution

The correct option is A 0°

From the first law of reflection, the angle of reflection is always equal to the angle of incidence.

We know that the angle of incidence is the angle between a ray incident on a surface and the surface normal or the line perpendicular to the surface at the point of incidence.

Given,
Incidence angle = 0°
Therefore, angle of reflection is 0°.
