Answer:
Option - (a) 10 cm
Explanation:
If the object is placed between the principal focus and pole of the mirror we will get a magnified virtual image. Here the image is formed behind the mirror and hence it is virtual. See the attached ray diagram.
The focal length of the given concave mirror is 15 cm. So, if the object is placed at a distance of 10 cm it will be between the focus and the pole.
