B) trichromatic theory.
C) three-opponent theory.
D) stage primary theory.

The trichromatic theory, also known as the Young-Helmholtz theory, explains color vision by stating that each of the cones in the retina contains a different type of iodopsin that responds to different wavelengths of light. When struck by light, the iodopsins break down and trigger action potentials, which are sent to the brain to create our perception of color. This theory suggests that colors are perceived based on the relative activation of the three types of cones (red, green, and blue).
