Which of the following body parts behaves like a stretched rubber sheet?

Eardrum

The correct answer is Option (4) -Eardrum

The body part that behaves like a stretched rubber sheet is the Eardrum. Also known as the tympanic membrane, the eardrum is a thin, cone-shaped membrane that separates the outer ear from the middle ear. It vibrates in response to sound waves, transmitting these vibrations to the middle ear, where they are then transmitted to the inner ear for processing. The eardrum's ability to vibrate and transmit sound waves is comparable to a stretched rubber sheet, allowing it to capture and transmit sound effectively.
