Solution

The correct option is C $50$ cm away
In this case, the mirror is moved 25 cm away from its initial position. Therefore, if the mirror is moved with distance x, then image in the mirror will move by distance 2x.
That is, 2x=50 cm.
So, the image will shift by 50 cm away from its previous position.
