Quizplus · Accepted Answer

Since Vince has color-deficient vision, he is either monochromatic (seeing in only shades of gray) or dichromatic (able to see in two primary colors instead of three). Therefore, choice C is correct. Additionally, since he does not realize his vision is different from others', we can rule out the possibility of being neither monochromatic nor dichromatic, making D incorrect.
