Solution

The correct option is D
At F₂ only

If the mirror were whole and complete then the image of an object at infinity will be at the focus (f).

Now if some parts of the mirror are blocked to form 3 mirrors as shown in the question, then the position of the image will not be affected. But the brightness of the image reduces (due to missing part of mirror).
