C. claiming that there is evidence showing that one of its premises is false
The biologist thinks that sea lice transmission is unlikely because the conditions in the archipelago "tend to suppress" sea-lice proliferation. The professor provides additional information, and then says that, actually, the conditions "favor theflourishing of sea lice."

Because the information provided by the professor completely contradicts the biologist's premise, we can determine that this additional evidence shows that the biologist's premise is false.
