b) What is the partition coefficient for benzoic acid between diethyl ether and water (at 20 °C and pH <2.8)?

Several stickleback species live in sympatry. These species exhibit morphological divergence as they each exploit either the benthic (bottom) or the limnetic (deeper, open-water) environment. Occasionally, the two kinds mate, resulting in hybrid offspring. Which of the following is a potential reason for maintenance of these two separate groups despite the occasional hybridization event?
A) Hybrids share traits of both species, and thus are specialized and able to hunt well in either environment.
B) Hybrids share traits of both species, and thus are able to attract mates of either species.
C) Hybrids share traits of both species, and thus are not specialized to either environment in terms of hunting.
D) Hybrids share traits of both species, and thus may not have specific traits to attract mates of either species.
E) Both A and B.
F) Both C and D.
