Answer:
A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.
C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.
Note - hope this is accurate :)
I cant tell you the answer since theres no picture but im guessing the steepest one out of all of them
