Choose the correct answer:

i) Assertion: The image falls on Fovea

ii) Reasoning: Because of refraction of light by vitreous humors

a. A is correct B is wrong

b. B is correct A is wrong

c. B explains A

d. A explains B.

c. B explains A

Explanation: human eyes project light to produce sharp images. Light rays from distant object are focussed on retina through cornea, aqueous humor, the lens and then to vitreous humor. The light rays show the phenomenon of refraction due to change in the refractive index of the different mediums. This is how light is focused on retina reaching fovea which have highest density of cone cells.
