An object is placed at the centre of curvature of a concave mirror. The distance between its image and the pole is

When an object is placed at centre of curvature of concave mirror than the real, inverted image of size same as that of object is formed at the center of curvature.

Therefore the image distance = Centre of curvature = 2f. Hence the correct option is C
