A student uses only colours to indicate correct and incorrect answers in a presentation. For whom may this create a problem?

Answer and explanation

Correct answer: For viewers with colour-vision difficulty

The governing concept is accessible visual communication. Colour alone is not a reliable code for every viewer because some people have colour-vision difficulty or may view the presentation under poor lighting. Option C is correct: adding labels, patterns, words, or symbols makes the distinction understandable without relying only on colour. A is too broad, while B and D identify people who are not the affected audience.
