B)1 = cornea, 2 = lens, 3 = fovea, 4 = retina 
C)1 = lens, 2 = cornea, 3 = retina, 4 = fovea 
D)1 = fovea, 2 = lens, 3 = cornea, 4 = optic chiasm

Quizplus · Accepted Answer

1 = cornea: the clear covering of the front of the eye
2 = lens: the transparent structure behind the iris that helps to focus light onto the retina
3 = fovea: the center of the macula (a part of the retina) that contains a high concentration of cones for detailed vision
4 = retina: the innermost layer of the eye that contains photoreceptor cells (rods and cones) that detect light and send signals to the brain
