The cones in the human eye are specialized photoreceptor cells that detect light and are responsible for color vision. There are three types of cones, each sensitive to different wavelengths of light corresponding to the colors red, green, and blue. This trichromatic theory of color vision states that our perception of color is based on the activation of these three types of cones.

When light enters the eye, it stimulates these cones to varying degrees depending on the wavelength of the light. The cones that are sensitive to red wavelengths respond to longer wavelengths, green cones respond to medium wavelengths, and blue cones respond to shorter wavelengths. This combination allows the brain to interpret a wide spectrum of colors. Therefore, the correct answer consists of the colors corresponding to the cone sensitivities: red, green, and blue.

The other choices provided do not accurately represent the full range of cones' sensitivity in the human eye. For instance, colors like orange, yellow, violet, or brown do not correspond directly to the primary sensitivities of the cones, highlighting why those responses are less accurate.
