The real image formed by a concave mirror is larger than the object when the object is:
(a) at a distance equal to radius of curvature
(b) at a distance less than the focal length
(c) between focus and centre of curvature
(d) at a distance greater than radius of curvature

(c) between focus and centre of curvature

Explanation

For an object placed between the focus (f) and the centre of curvature (c), the image formed will be real and larger than the object.
