Answer :
Final answer:
The outer and middle ears transmit a pressure wave from air to fluid through compression, rarefaction, and vibration. So, the correct option is C.
Explanation:
The three ways in which the outer and middle ears transmit a pressure wave from air to fluid are compression, rarefaction, and vibration. When a sound wave enters the ear, it first reaches the outer ear, which consists of the pinna (the visible part of the ear) and the auditory canal. The pinna acts as a funnel, directing the sound waves into the auditory canal. As the waves travel down the auditory canal, they reach the tympanic membrane (eardrum).
When the sound waves strike the eardrum, they create compression and rarefaction in the air inside the middle ear. These pressure changes cause the eardrum to vibrate back and forth. The vibrations of the eardrum are then transmitted to the ossicles (three small bones in the middle ear), which further amplify the sound before passing it on to the inner ear.
