Explanation
In the human eye, the image of an object is formed at the A: Retina.
The retina is the innermost layer of the eye that contains light-sensitive cells called rods and cones. When light enters the eye, it is focused by the cornea and lens onto the retina, which then converts the light into electrical signals that are sent to the brain through the optic nerve. The brain then interprets these signals and creates the perception of an image. The retina is responsible for the sharpness and clarity of the image that we see. Problems with the retina, such as damage or disease, can affect our vision and lead to vision loss.
