Quizplus · Accepted Answer

The fovea is a small area in the center of the retina that contains a high concentration of cone cells, which are responsible for sharp, detailed vision. It is not where the optic nerve leaves the eye (which is the optic disc), and it does not contain many rod cells (which are responsible for low-light vision). Therefore, choice A is the best answer.

The Fovea
