Correct Answer: Option A
Explanation

Center of Curvature: For a concave mirror, the center of curvature (C) is located at twice the focal length. With a focal length of 5 cm, C is at 10 cm.

Object Placement: The object is placed at 10 cm, which is exactly at the center of curvature.

Image Formation: When an object is at the center of curvature, the image is also formed at that same point, resulting in a real and inverted image

(When the object is located at the center of curvature, the image will also be located at the center of curvature.)(For concave mirror)

There is an explanation video available below.
