Solution
The correct option is B Lens
Lens is a
transparent material bound by two surfaces, of which one or both surfaces are
spherical.
It may have two
spherical surfaces, bulging outwards called convex lens and can have two
spherical surfaces, curved inwards called concave lens. It may also have a plane and a spherical surface as in plano-convex lens.
