Solution

The correct option is D

remains same


  1. The size of the image does not change when the mirror is rotated
  2. It depends on the magnification which is independent of rotation.
  3. So, there will be no change in the size of the image due to the rotation of the mirror.

Hence, the correct option is (D).
