Question

Quizplus · Accepted Answer

The trichromatic theory of color vision suggests that color vision is based on the response of three types of cones, one primarily sensitive to short wavelengths, one to medium wavelengths, and one to long wavelengths. People who lack sensitivity in their long-wavelength cones are most likely to suffer from colorblindness, which is why the best choice is D.
