Color vision has much greater resolution than night vision (vision that is mostly in shades of gray). Which of the following is the best explanation for why this is so?
A) A single cone photoreceptor often connects to a single bipolar cell and a single ganglion cell while as many as 100 rods will converge to a single ganglion cell.
B) There are several types of cone photoreceptors, each of which enrich the clarity and resolution of vision.
C) A larger proportion of the brain's visual cortex is active during the day when our cone photo receptors are most active.
D) There are many more cone photoreceptors in the eye than rod photoreceptors.
