The correct option is C Concave, plane and convex Concave mirror produce an enlarge and erect mirror As the head is larger ,the mirror must be concave, plane mirror does not change the image hence middle region is plane mirror , Convex mirror produce an erect and diminished image hence bottom half is convex mirror.As the head is larger so top portion must be concave mirror hence the top portion cannot be convex or plane mirror.Hence, Option C is Correct.
