Rods function well in low light and cones do not because:
A) the axons of many rods converge before reaching the optic nerve.
B) rods send their messages on single nerve fibers to the optic nerve.
C) the axons of cones converge before reaching the optic nerve.
D) cones are in the center of the retina and rods are near the periphery.

The axons of many rods converge before reaching the optic nerve, which allows for greater sensitivity to low levels of light. This convergence also results in less visual acuity and difficulty discerning fine details. Cones, on the other hand, have a one-to-one connection with the optic nerve and provide better visual acuity and the ability to discriminate colors, but are less sensitive in low light conditions.
