Solution

The correct option is C $0^{\circ}, 0^{\circ}$
When light incident perpendicular to the plane mirror i.e along with the normal, angle of incidence (angle between ray and normal) is zero.
From first law of reflection. Angle of incidence, $i =$ Angle of reflection, $r$
So, Angle of reflection $= 0^{\circ}$
