Which colors are the cones of the human eye sensitive to?

The correct answer highlights the three primary colors that the cones in the human eye are specifically sensitive to: red, green, and blue. These cones are essential for color vision and allow us to perceive a wide spectrum of colors through a process known as additive color mixing. Each type of cone is sensitive to a different part of the light spectrum; one type responds to short wavelengths (blue), another to medium wavelengths (green), and the third to long wavelengths (red). When these cones are stimulated in various combinations, the brain interprets the signals, enabling us to see a broad array of colors.

The other options either include colors that are not directly linked to the cone sensitivities in the human eye or include color combinations that do not align with the scientific understanding of human color perception. For instance, yellow is not a primary color in the context of cone sensitivity, and colors like purple or black do not correspond to the cone types or their wavelength sensitivities in the eye.
