A) = 10 cm, real, smaller than object
B) = 10 cm, virtual, smaller than object
C) 20 cm, real, larger than object
D) = 20 cm, real, same size as the object
E) = 20 cm, virtual, same size as the object

When an object is placed between the center of curvature (C) and the focal point (F) of a concave mirror, the image formed is beyond the center of curvature (C), real, inverted, and larger than the object. Since the focal length is 10 cm, the center of curvature is at 20 cm, so the image is formed at a distance greater than 20 cm from the mirror.
