d the ossicles conduct vibrations across the inner ear.

Explanation:

• Option A: Conductive hearing loss is indeed due to outer or middle - ear issues.
• Option B: In the cochlea, fluid vibrations stimulate hair cells which in turn stimulate nerve endings.
• Option C: Sensorineural hearing loss is caused by inner - ear or cochlear nerve damage.
• Option D: The ossicles (malleus, incus, stapes) conduct vibrations across the middle ear, not the inner ear.
