If both red-yellow-blue and red-green-blue are given in an exam question about primary colours, what should determine the correct choice?

Answer and explanation

Correct answer: Whether the question refers to painting or light

The governing concept is that different colour systems use different primary sets. In traditional subtractive painting, red, yellow, and blue are commonly taught as the primary colours; in additive light, red, green, and blue are the primary channels. Consequently, the wording and context must determine the answer, so option A is correct. Option order, option length, and spelling are test-taking details with no scientific connection to the colour model.
