Solution

The correct option is C all mirrors irrespective of their shape
We know that from the laws of reflection, the incident ray, the reflected ray, and the normal to the reflecting surface all lie in the same plane. Also, the angle of reflection is equal to the angle of incidence.
The laws of reflection hold good for all reflecting surfaces irrespective of their shapes whether plane or curved.
