Answer

Brief Explanations:

The opponent - process theory of color vision posits that there are three pairs of opposing color processes in the visual system (red - green, blue - yellow, black - white). When you stare at a red object for a long time and then look at a white surface, the red - sensitive cells become fatigued, and the opposing green - sensitive cells are more active, resulting in a greenish after - image. This phenomenon is consistent with the opponent - process theory. Hering's vibration is not a recognized theory in color vision. The Helmholtz trichromatic theory emphasizes three types of color - sensitive cones but does not explain after - images as well as the opponent - process theory. There is no well - known "Grieco trichromatic" theory in color vision.

Answer:

B. the opponent - process
