Which colours should a student choose to make orange?

Correct answer: Red and yellow

The governing concept is primary-to-secondary colour mixing. In the traditional subtractive art system, orange is made by mixing the primary colours red and yellow. Yellow plus blue produces green, while red plus blue produces violet; these pairings are the relevant distractors. Green and blue are not the standard primary pair for making orange. Therefore, option A is correct. The exact result can vary slightly with pigment properties and proportions, but the basic school-level rule remains red plus yellow equals orange.
