    • Auricle

    • Ear Drum

    • Cochlea

    • Tympanic membrane

    Correct Answer
    A. Ear Drum
    Explanation
    The correct answer is Ear Drum. The ear drum, also known as the tympanic membrane, is a thin, sensitive membrane that separates the outer ear from the middle ear. When sound waves enter the ear, they cause the ear drum to vibrate. These vibrations are then transmitted to the middle ear, where they are further amplified and transmitted to the inner ear. The vibrations in the ear drum are converted into electrical signals that are sent to the brain, allowing us to perceive and hear sounds.
