Visual acuity is sharpest when images cast by environmental stimuli fall directly on the fovea because
A) each cones synapses directly onto a single ganglion cell and there is concentration of cones in the fovea.
B) there are fewer bipolar and ganglion cells in the area surrounding the fovea than there are in the area surrounding the retina's periphery.
C) there are no photoreceptors in the retina's periphery.
D) the fovea has no blind spot.
E) the distance between the retina and the optic nerve is minimized at the fovea.

The fovea has a high concentration of cones, which are responsible for sharp, detailed vision, and each cone synapses directly onto a single ganglion cell, allowing for precise visual acuity.
