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.

So the numbers in the middle will be reversed and their shape will also be changed, thus the first and third options will be eliminated.

Also, in the question figure, the arrow at bottom right (pointing upwards) will appear at bottom left side still facing up, hence fourth option is the right image.

=> Ans - (D)
