Answer:c...radius of curvature
Explanation:when an object AB is placed at radius of curvature(C),the ray of light coming from top of object A goes parallel to principal focus...strikes concave mirror and goes along focus...again the ray of light from point A goes from centre of curvature and does two rays of light strikes and thus A'B' image is formed which is of equal size of object
