Final answer:
A lens that can cure myopia is either a diverging lens or a concave lens. Both of these names refer to the same type of lens that helps spread the light rays so they focus onto the retina.
Explanation::
The correct answer is
d) Both a and c.
A lens that can cure myopia is a diverging lens or a concave lens. This type of lens helps spread the light rays slightly so that they focus onto the retina. In myopia, the images are focused in front of the retina, and a concave lens is used to correct this condition. Another name for a concave lens is a diverging lens, which always causes light rays to bend away from the principal axis.
