What is the difference between a fish eye and a mammal's eye, and in what way might this be explained?
A) The fish eye has only one light-bending element; the mammal eye has two. This is because the human eye is more advanced than the fish eye.
B) Fish eyes have multiple light-bending elements in order to see in water, while mammal eyes have only one.
C) The fish eye has only one light-bending element; the mammal eye has two. This allows fish to have more light-gathering ability and mammals to have greater distance vision.
D) Mammals have two light-bending elements, while the fish eye makes use of the surrounding water to act as a second "lens," so it can have only one light-bending element.
