Answer 1

The correct answer is "it receives incoming sound information and directly stimulates the auditory nerve to transmit information to the brain."

Cochlear implants function to bypass the damaged cochlea due to sensorineural hearing loss (i.e. chronic noise exposure). Cochlear implants functions just like the hair cells and capture sound and transmit it via the vestibulocochlear nerve or the cranial nerve VIII and then to the temporal lobe in the auditory cortex.
