Tributyltin (TBT) is a chemical used to prevent barnacles from clinging to ships. Its use has been linked to whale deafness, where the hair cells do not function properly. Since whales depend heavily on hearing for navigation and hunting, hearing loss can lead to whales being washed ashore. Assuming that the whale ear structures are similar to those of humans, identify the structure that would be affected by TBT in the image below. Select one: a. Number Structure 7 Auditory nerve b. Number Structure 8 Semicircular canals c. Number Structure 6 Organ of Corti d. Number Structure 4 Ossicles
