Solution
The correct option is C Concave
Concave mirrors are used in torches used at homes or by dentists.
In a torch, the bulb is placed at the focal point of the concave mirror so the light from the bulb is reflected as a parallel beam. This helps users to specifically see the object, upon which the beam falls.
