Why is mixing coloured light different from mixing paints?

Answer and explanation

Correct answer: Light mixes additively while pigments mix subtractively

The governing concept is the difference between additive and subtractive colour systems. Coloured light adds wavelengths reaching the eye, so combining lights can increase brightness. Paint pigments absorb selected wavelengths, so combining paints subtracts more light from reflection. Thus option D is correct; the other choices make irrelevant or false claims about black, sound, or paper.
