Answer:Cochlea implants could consist of both a percutaneous plug and magnetic couplings. Correct option is B.
Explanation: Cochlea implants are hearing aids which are surgically implanted to provide a person with moderate to profound sensorineural hearing loss, a modified sense of sound. The implant has two components:
- percutaneous plug: This makes up the outside component which is generally worn behind the ear.
-magnetic couplings. This makes up the inner component which is generally implanted inside the skull.
Hope this helps. Thanks.
