If a student says red and blue make green what is the correct correction?

Correct answer: Mixing red and blue makes violet

Under the traditional school colour-wheel model, red and blue are primary colours; mixing them produces violet, a secondary colour. Green is made by mixing yellow and blue, while orange comes from red and yellow. Therefore A corrects the student accurately. Option D simply repeats the misconception, and B and C assign the wrong mixtures. The answer assumes the standard subtractive art-painting model used in elementary colour theory.
