Why can red be considered a secondary colour in printing?

Answer and explanation

Correct answer: It is formed from magenta and yellow inks

The governing concept is subtractive colour mixing in the CMY printing system. Magenta absorbs greenish light and yellow absorbs bluish light; together they reflect mainly red, so the result is red. Therefore option A is correct. Cyan plus yellow produces green, while red light belongs to an additive light system rather than an ink mixture. Colour labels depend on the medium being studied.
