Answer: Fred stares at a green book for a minute, and then when he looks at a white page, he sees the color red

According to opponent process theory, when the eye is exposed to a primary color for some time, neurons of opposition become active and produce opposite signal which creates its perception. In this case, Fred looks at a green book that dulls the green color receptors. When he then gazes upon a white sheet when no after-images are present, the red cones that have not fatigued dominate and his eyes perceive “opponent” colour – The red. This is a classically demonstrated opponent processing caused by optic contrast and color receptor adaptation. Among all four answer choices, dark adaptation versus light perception describes the functioning of variety colors that is different from opponent processes; color vision does not refer to afterimages and sluggish pupillary responses—the second greatest exemplification of these attributes belongs to option A .
