When using a concave mirror as a shaving mirror, where should the item be placed?

 

Concave mirrors have a curved interior surface on the reflecting side.

These mirrors provide real and virtual images of the item, inverted and upright, expanded and reduced.

A virtual, upright, and enlarged picture is created when an item is put between the focus and the pole of a concave mirror. As a result, a concave mirror-based shaving glass is used. 

Hence option (B) is correct.
