C. Young-Helmholtz

Explanation:

The young Helmholtz theory also called as the trichromatic theory of color vision and gives rise to the phenomenological experience of color and on the basis of the photoreceptors that are found in the three types of the cones cells in the eye and each is sensitive to a special spectrum of visible light. These are classified as in short as red, green and violet according to the responses of the wavelengths of the lights that strike the retina and is detected by the cone and is interpreted by the brain.
