Thanks for the questions @djayasinghe @avggmc @Eden

The claim we are trying to evaluate is whether "the deformity in the bluefin cod must have been cause by the presence of those chemicals inCod Bay."

Let's go through the answer choices.

A and B go directly to the causal link between the chemicals and the deformities.s

D and E offer alternate explanations, besides the chemicals, for the cods' deformities.

Hope this helped! Let me know if you have any further questions.
