answer : mirror ‘B’ can be used as dentist mirror.
explanation : magnification of mirror A is +1 , it means mirror is not other than plane mirror.
magnification of mirror B is +5, it means mirror B is a concave mirror, because we know, when object is placed between force and pole of concave mirror, it makes magnified image other side of mirror.
magnification of mirror C is +0.45 < +1 , it's not other than convex mirror. as you know, magnification of convex mirror is always positive but less than 1.
as you know, dentist uses concave mirror. and here mirror B is concave mirror so, answer is mirror 'B'.
