Detailed explanation-1: -A plane mirror always forms a virtual image of an object, because the image formed by a plane mirror cannot be obtained on the screen.

Detailed explanation-2: -Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. When some of the light rays enter our eye, our eye and brain interpret these rays as having traveled in a straight line path.

Detailed explanation-3: -(b) a convex mirror always produces a virtual image independent of the location of the object.

Detailed explanation-4: -Concave mirrors can produce both real and virtual images depending on the distance from the mirror to the object and the curvature of the mirror, while convex mirrors produce only virtual images.
