Which of the following is an explanation for the higher acuity of the visual system at the fovea, relative to the periphery of the retina?
a. A foveal ganglion cell may receive information from a single photoreceptor, whereas a
peripheral ganglion cell may receive information from multiple photoreceptors.
b. The fovea contains only rods, which are directly connected to the ganglion cells.
c. Peripheral photoreceptors are more likely to be damaged by prolonged light exposure.
d. The foveal photoreceptor cells contain more photopigment per cell.
e. Peripheral photoreceptors are more isolated from bipolar cells and thus require greater activation in order to provoke a visual response.

Visual acuity if greater at the fovea than the periphery insasmuch as a foveal ganglion cell may receive information from a single photoreceptor, whereas a peripheral ganglion cell may receive information from multiple photoreceptors.
