A) production of the photopigment rhodopsin in photoreceptors is increased.
B) the rate of neurotransmitter released from photoreceptors is decreased.
C) the plasma membranes of photoreceptors become depolarised.

When the vertebrate retina is exposed to light, the rate of neurotransmitter release from photoreceptors is decreased. This is because light exposure leads to hyperpolarization of photoreceptor cells, reducing their release of neurotransmitters.
