Correct Answer

Explanation

For plane mirror images size = object size therefore magnificationimage size = 1 object size
The magnification of an object when placed in front of a plane mirror is always 1. This means that the image formed by the mirror is the same size as the object and appears at the same distance behind the mirror as the object is in front of it. So, in this case, the magnification would be 1.
