Answer:
The correct answer is option A, Plane Mirror
Explanation:
A plane mirror has a flat surface while remaining concave and convex mirror have bulging surfaces. A concave mirror is a converging mirror while a convex mirror is a diverging mirror. Having a planar surface, the angle of incidence and reflection is equal in a plane mirror. There is nothing like a virtual mirror however the mirrors have the ability to form virtual image.
Thus among all the options, option A is correct
