Answer: (D)

Verified step by step guidance

1. Understand the function of cochlear implants: Cochlear implants are medical devices designed to help individuals with severe hearing loss by bypassing damaged hair cells in the cochlea and directly stimulating the auditory nerve.
2. Review the components of cochlear implants: They consist of both external components (such as a microphone and speech processor) and internal components (such as electrodes implanted in the cochlea).
3. Clarify the limitations of cochlear implants: While they provide a sense of sound and improve hearing, they do not fully restore normal hearing in all patients. The quality of sound perception varies depending on individual factors.
4. Analyze the statements provided: Compare each statement to the known facts about cochlear implants. Identify which statement is inconsistent with the scientific understanding of cochlear implants.
5. Conclude that the false statement is: 'Cochlear implants can fully restore normal hearing in all patients,' as this is not accurate based on the limitations of the device.
