Sensory Input from the Eyes and Ears Travels in Neurons

Sensory input from the eyes and ears travels in neurons to the brain. Why are the different stimuli perceived as light and sound?

A) because the sensory receptors themselves are different
B) because the physical locations of the sensory receptors are different, ensuring a different "sense" is perceived in the brain
C) because information from each type of receptor is sent to a different region of the brain
D) because light receptors send neural impulses more frequently than sound receptors
