hello mate

answer will be A)half of radius of curvature

explanation:::::Proving the focal length is half the radius of curvature:

Taking a concave mirror, the curved mirror will have a principal axis near which a ray of light is incident on the mirror parellel to it. ... Hence, in both cases Radius is double the focal length.
