The wavelength of the visible spectrum falls between 400 and 700 nanometres (nm), with 400 being the shortest and 700 being the longest. Chlorophyll is a green pigment that is used in photosynthesis. Chlorophyll is what makes the leaf of a plant appear green because chlorophyll reflects green light. It absorbs red and blue light for photosynthesis. The wavelength of red light falls between 600 and 700 nm, green light falls between 500 and 600 nm, and blue light falls between 400 and 500 nm.
Choice A is incorrect because it includes blue and green light in the “absorbed” category. Choice B is incorrect because it includes only red light in the “absorbed” category. Choice D is incorrect because it includes green light in the “absorbed” category. Only Choice C is correct because it includes red and blue light in the “absorbed” category.
