Solution

The correct option is B A diverging glass because it produces a broader range of light
A diverging glass is used in making of a torch light , diverging lens or concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light waves curve outward or divergeand spread out into the distance means it produces a broader range of light.
