Based on the passage, which of the following can be inferred about the chromophores referred to in the final sentence of the passage? A. If exposed to light with wavelengths of approximately 300 nm, they will scatter the radiation. B. If exposed to light with wavelengths in the 290-320 nm range, they will lower the energy level of some of their constituent electrons. C. If exposed to light waves in the 290-770 nm range, they will absorb the photons and emit them as light of longer wavelengths. D. If exposed to light with wavelengths of approximately 300 nm, some electrons in their component molecules will switch to higher energy levels. E. If exposed to light waves in the 290-320 nm range, they will promote the discrete quantal amounts of energy that are required to excite electrons between energy levels.
