The image shown in the code is a type of Ishihara plate, which is used to test for color deficiency (also known as color blindness). Option B is incorrect because a rod monochromat is a type of color deficiency, so someone who is a rod monochromat would already know they have a color deficiency without needing to take this type of test. Option C refers to a Hering image, which is a different type of color vision test. Therefore, the best choice is A, as it correctly identifies the type of image and the purpose for which it is used.
