The opponent-process theory of color vision proposes that there are three types of color channels in the retina, each of which contains opposing pairs of colors: red-green, blue-yellow, and black-white. This theory suggests that color vision is based on the comparison of the output between the pairs of color channels, and it is driven by differences in the firing rates of the corresponding retinal cells. Therefore, choice C is the best option as it reflects this idea.
