According to the opponent-process theory, there are three cone types that respond to different wavelengths of light and result in three primary colors - red, blue, and green. These three colors are then combined and processed in opposing pairs (red-green, blue-yellow, and black-white) to create the perception of all other colors. Therefore, the total number of chromatic/achromatic colors is six (three primary colors and three opponent pairs) and they are organized into three opponent-process pairs. So, option D (six; three) is the correct answer.
