The nerve impulse sent to the brain from the ear originates from B. the hair cells on the organ of Corti.

Here's a step-by-step explanation:

1. Sound waves enter the ear and vibrate the eardrum.
2. These vibrations are then transferred to the three small bones in the middle ear: the malleus, incus, and stapes.
3. The stapes bone pushes on the oval window, which leads to the cochlea in the inner ear.
4. The movement of the oval window creates waves in the fluid-filled cochlea.
5. These waves cause the basilar membrane to move, upon which sits the organ of Corti.
6. The organ of Corti contains tiny hair cells that move with the waves.
7. As these hair cells move, they generate an electrical signal or nerve impulse.
8. This impulse is then sent to the brain via the auditory nerve, where it is interpreted as sound.
