Detailed Solution

Mirror B is used to check shop-lifting
Fig. 2 shows a convex mirror. Convex mirrors are used to check to shoplift and for security purposes. This is because a convex mirror produces a wider field view when compared with a plane mirror and a concave mirror. Convex mirrors are also called diverging mirrors, fisheye mirrors or dome mirrors. It is highly suitable for security applications in shops, malls and retail stores. An appropriately fixed convex security mirror provides a wide-angle view.
