In the following question, 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 square with 'X' sign at top left will now appear at top right, thus the third option will be eliminated. Also, the arrow underneath it will still face upwards, and thus the second option is also eliminated.

Also, in the question figure, in the middle row, at rightmost side, '(' will be changed to ')', hence fourth option is the right image.

=> Ans - (D)
