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 triangle (pointing downwards) at top left will be reversed and will face downwards at top eight position, thus the last two options will be eliminated.

Also, in the question figure, the parallelograms at right diagonal position will shift top left diagonal and will change their shape, hence first option is the right image.

=> Ans - (A)
