Which statement correctly explains why a convex mirror invariably produces a virtual image whereas a convex lens can produce a real image?
(a) The focal length of a convex mirror is negative, whereas that of a convex lens is positive; a negative focal length cannot give a real image.
(b) For a convex mirror the object is always located inside its focal length, while for a convex lens the object can be placed beyond the focal length.
(c) Reflected rays from a convex mirror diverge after reflection, whereas refracted rays through a convex lens converge after refraction.
(d) A convex mirror has only one reflecting surface so the light is deflected once, but a convex lens bends light twice, enabling the rays to meet and form a real image.
