When Abrams and Townsend Investigated the Natural Selection of Copepods

When Abrams and Townsend investigated the natural selection of copepods that avoid predation of bioluminescent dinoflagellates,which of the following best states the hypothesis they were testing?

A) The bioluminescent dinoflagellates produce enough light that they can also photosynthesize at night, harming the copepods.
B) Copepods that avoid bioluminescent dinoflagellates have a smaller chance of being eaten by predators than do copepods that remain near and feed on the bioluminescent dinoflagellates.
C) The light emitted by bioluminescent dinoflagellates is of sufficient wavelength and energy to be dangerous to feeding copepods.
D) None of the answer choices are correct.
E) Bioluminescent flagellates benefit from selection of flashing, because it startles the copepods.
