A)greater hyperpolarization
B)less hyperpolarization
C)greater depolarization
D)less hyperpolarization

When a rod is exposed to bright light, it undergoes a greater amount of hyperpolarization, meaning that the potential difference across the cell membrane increases to a greater extent than when exposed to dim light. This is due to the larger amount of photons being absorbed by the rod cells under bright light conditions, which leads to a greater activation of the phototransduction cascade and ultimately more hyperpolarization of the cell.
