Answer:
(i) - Mirror A will form a diminished image of the object. Because the object is much far from the mirror.[more than twice it’s focal length(2f =2* 20=40) ]
(ii) - Mirror C can be used as a Makeup mirror. Because the object is placed at a distance less than its focal length producing virtual and enlarged image.
