• A. suggested that color vision is made possible by red, blue, and green cones.
• B. theorized that light is made up of four primary colors.
• C. suggested that color vision is made possible by red, yellow, and blue cones.

Answer: (A)

Verified step by step guidance

1. Understand the context of Thomas Young's theory of color vision, which is a foundational concept in the study of how humans perceive color.
2. Recognize that Young's theory is often associated with the trichromatic theory of color vision, which posits that there are three types of color receptors (cones) in the human eye.
3. Identify the three primary colors according to Young's theory, which are red, green, and blue. These correspond to the three types of cones in the retina that are sensitive to different wavelengths of light.
4. Differentiate Young's theory from other theories of color vision, such as the opponent-process theory, which involves different mechanisms for color perception.
5. Conclude that Thomas Young's theory suggested that color vision is made possible by the presence of red, blue, and green cones in the eye, which aligns with the trichromatic theory.
