Solution
The correct option is C Concave lens
Myopia is a defect in which the image is formed in front of the retina instead of on the retina because of the long eyeball or high converging power of the eye lens. Since a concave lens is a diverging lens, it is placed in front of the eye to diverge the light rays before entering the eye lens in order to form the image on the retina as shown below.
