The correct answer is (D) -37.5 cm.
Explanation:
Using the mirror formula 1/f = 1/v + 1/u , where:
f = -15 cm (focal length of concave mirror),
u = -25 cm (object distance placed in front of the mirror).
The calculated image distance (v) is -37.5 cm, indicating that the image is formed 37.5 cm in front of the mirror on the same side as the object.
