If a person is standing in front of a mirror and his left hand is on the right side and the right hand is on the left side. What kind of mirror he is looking at?

The correct option is D

All of these

In an image formed by any mirror, the left side of the object appears to be on the right side and the right side of the object appears to be on the left side. This is called lateral inversion.

Lateral inversion is defined as the apparent reversal of the mirror image's left and right when compared with the object. Lateral just means sideways. It is applicable for all types of mirrors.
