Answer Details
When an object is placed at the center of curvature of a concave mirror, the image formed will be real, inverted and the same size as the object. So, the correct option is (E) "at the center of curvature". The light rays from the object will fall parallel to the principal axis of the mirror, and after reflection, they will converge at the center of curvature. The image formed will be located at the same distance from the mirror as the object, and it will be inverted and real.
