A)It will be excited.
B)It will be inhibited.
C)It will be both excited and inhibited.
D)It will be neither excited nor inhibited.

According to opponent-process theory, activation of L cones, which respond to long wavelengths of light (red), would lead to inhibition of the ganglion cell that receives excitatory input from cones detecting short wavelengths of light (blue). This is because the blue-yellow opponent process is active in the visual system, where activation of one cone type leads to inhibition of the opposing cone type. Therefore, the ganglion cell receiving excitatory input from blue cones would be inhibited by the activation of L cones that detect long wavelengths of light.
