C)sight in order to locate dying fish and annelids,molluscs,and crustaceans.

E)All of the choices are well-developed in hagfish

Accepted Answer

The hagfish primarily uses its keen sense of smell and touch to locate dead and dying fish, which it scavenges on, making choice B the best option. While the hagfish does have a swim bladder, there is no evidence to suggest that it has a particularly acute sense of depth or water pressure control, making choice A less likely. Similarly, the hagfish is primarily adapted to dark, deep-sea environments, so its eyesight is likely not as well-developed as its other senses, making choice C less likely. While the hagfish is believed to have some ability to detect sound, it is not primarily adapted to use its hearing to locate prey, making choice D less likely. Finally, while the hagfish is known for having a well-developed sense of smell, it is not clear that all of the choices listed are equally well-developed, making choice E less likely.
