Which of these statements are correct: Read carefully
Sound waves create vibrations of the tectorial membrane which have a knock on effect on the incus, malleus and stapes respectively, this pushes the round window and causes ripples in the endolymph of the Scala tubes
Sound waves create vibrations of the tympanic membrane which have a knock on effect on the incus, malleus and stapes respectively, this pushes the oval window and causes ripples in the perilymph of the organ of Corti
Sound waves create vibrations of the tympanic membrane which have a knock on effect on the malleus, incus and stapes respectively. this pushes the oval window and causes ripples in the perilymph of the Scala vestibule and subsequently the Scala tympani
