Biologist Dr. Hayashi proposes that some fish species use specific facial markings to recognize individual schoolmates, as opposed to merely distinguishing fish in general from non-fish.
Which finding, if true, would most strongly support Dr. Hayashi's proposal?

- B
Many fish species have distinctive markings.
- C
Some fish species swim in tightly coordinated schools.
- D
