Image formed by a plane mirror is:
$(a)$. virtual, behind the mirror and enlarged.
$(b)$. virtual, behind the mirror and of the same size as the object.
$(c)$. real at the surface of the mirror and enlarged.
$(d)$. real, behind the mirror and of the same size as the object.

The correct answer is: $(b)$. virtual, behind the mirror, and of the same size as the object.


Explanation:

Let us know a little about the image formation of an object by a plane mirror:

Image formation by a plane mirror:

The image of an object formed by a plane mirror is virtual, erect $(upright)$, of the same size as the object, at the same distance behind the mirror, and laterally inverted. The virtual images form when the light rays appear to meet at a definite point, after reflection from the mirror, and they can never be captured or obtained on a screen.

Ray diagram:

To represent the image formed by a plane mirror a ray diagram is given below. Let us see how the image of an object is formed:
