Solution

The correct option is A

concave


  1. Concave mirrors are used by dentists because they are converging mirrors and reflect light to the focal point.
  2. While convex mirrors make things appear smaller, concave ones magnify the images.
  3. The surface of a concave mirror is bent inward and outward. By using this type of mirror, dentists can see the tooth larger if there is any infection or germ attack happening.

Hence, option A is correct.
