Why can two different sets of primary colours both be useful?

Answer and explanation

Correct answer: Primaries depend on medium and purpose

The governing concept is that primary colours depend on the colour system and medium. Red, yellow and blue are commonly taught for traditional painting, while light and printing systems use different primaries such as RGB or CMY. Therefore, two sets can both be useful when they serve different purposes. Option A is correct; the other choices incorrectly treat one system as universally right or rules as meaningless.
