According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with red, green, and blue. Therefore, option "C" is correct. According to the trichromatic theory of color vision, the human eye perceives only three hues of light which are green, red, and blue.
Every color in the visible light spectrum can be produced by combining the wavelengths of these three colors. Thomas Young first proposed trichromatic theory, and Hermann Von Helmholtz later tested it. Each of these three kinds of cones responds to distinct wavelengths of light, which, when combined, can be used to produce all of the colors in the visual spectrum.
