Which receives vibrations from the stapes and sends them to the cochlea?

Explanation:
When sound energy enters the inner ear, the stapes pushes on the oval window, launching vibrations into the inner-ear fluids. The vestibule is the inner-ear chamber that first receives those vibrations from the oval window and channels them onward toward the cochlea. From there, the waves travel through the cochlea’s fluids and ultimately stimulate hair cells to generate nerve signals. The cochlea itself is where transduction happens, not the initial recipient of the stapes’ vibrations. The malleus handles vibrations from the eardrum, and the Eustachian tube mainly equalizes pressure. So the vestibule best fits the described role.
