Which option correctly shows a primary colour and a secondary colour made using it?

Correct answer: Red and Orange

Option D is correct because orange is a secondary colour made by mixing red and yellow, so red is one of its primary components. The pair does not claim that red alone produces orange; it shows that orange includes red in its mixture. The other pairs do not express the intended direct component relationship in the traditional colour wheel: violet uses red and blue, green uses blue and yellow, and orange uses red and yellow.
