If a mirror is placed on the line MN, then which of the answer figures is the right image of the given figure ?

A vertical mirror is placed, so the object on the left will appear right in reverse position and vice-versa.

Of the three sections of the rectangle, in the first two sections, the dot is in the left side of the boxes, so in the mirror they will appear at the right sides, and similarly in the last section, the dot will appear in the left side of the box, hence fourth option is the correct mirror image.
