A)by the bones of the middle ear
B)through the oval window
C)by the tympanic membrane
D)by the action of the vestibular system

The sound vibrations are transferred to fluid pressure waves through the oval window, which is a membrane that separates the middle and inner ear. The sound waves travel through the auditory canal and vibrate the tympanic membrane, which then transfers the vibrations through the bones of the middle ear to the oval window, causing fluid pressure waves in the cochlea.
