Blue whales congregate off the coast of Canada each year when large numbers of certain small fish gather to spawn. Blue whales are known to be highly social, using a wide range of loud sounds to communicate over great distances. Some of their most boisterous sounds have been recorded while they are feeding, which leads scientists to believe that they occasionally exhibit pack hunting behavior, not unlike wolves and killer whales.
Which of the following, if true, most seriously calls into question the explanation given for the blue whale's behavior off Canada's coast?
A. Blue whales go months at a time without finding sufficient sources of food.
B. Adult blue whales in the same pod have been known to coordinate their movements to protect their youngest members from killer whale attack.
C. Sudden loud sounds can confuse and disorient small fish.
D. The fish in the argument see the whales as a predator and do their best to avoid them.
E. Blue whales do not typically emit the same sounds when they are feeding on krill in more tropical regions.

I am not sure how C applies here.
Sudden sounds CAN; this doesn't mean they generally/tend to confuse prey.
Also, the passage talks about sounds emitted during feeding, not hunting and the conclusion is that they hunt in packs.
