The answer is D. Both the Trichromatic theory and the opponent-process theory have to do with color reception and activation of photoreceptors, which are located in the retina. Opponent-process theory has to do with the fact that certain certain color pairs cannot be seen together at the same time, like bluish yellow and reddish green. Hope this helps
