    None of the above. Absorption by chlorophyll is in the red and blue ranges, so B) is the closest choice.

    Plants are green because they reflect green (550 nm) light and absorb energy from the violet-blue (380-480 nm) and reddish-orange (600-680 nm) wavelengths at the opposite ends of visible light spectrum.
