Answer Key / Explanation : (b) -

(b)

Hyperopia (hypermetropia) is corrected with a converging lens. It relaxes when the eye focuses on a distant object. The main refractive element of the eye is the cornea, the lens is the focusing element. When the eye is focused on a near object the ciliary muscle contracts.
