When Your Eyes Are Exposed to More Light, the Pupils

When your eyes are exposed to more light, the pupils constrict limiting the amount of light entering the eye, and as a result the photoreceptors in the retina reduce the amplitude of the resulting graded potentials. What is the most likely reason for this response?

A) to reduce exposure of photoreceptors to unnecessary sensory information
B) to maximize visual clarity by selectively choosing which receptors are activated
C) to minimize sensory overload in the visual processing region of the brain
D) to allow the retina to focus on very specific areas that are illuminated
