The right answer is D. red and blue light.
Most oxygenated photosynthetic organisms use visible light, however, they are only active at certain wavelengths (i.e. they absorb these wavelengths by their photosynthetic pigments) for chlorophyll a , the spectrum of action includes blues and reds (wavelengths around 440 and 680nm), other pigments absorbing other wavelengths such as chlorophyll b, xanthophylls, or even carotenoids, play a role in photosynthesis, some photosynthetic organisms use the near infrared or, more particularly, the far red (around 800 nm wavelength).
