Solution

The correct option is D stretched membranes
Answer is D.
Sounds can be made by vibrating an object. For example, when a drumstick hits a drum, the flexible skin of the drum vibrates up and down. The skin's vibration makes a sound by moving the air above it. When the skin moves up, the air above it is compressed and when the skin moves down the air moves with it and expands.
Hence, the stretched membranes produces sound from a drum.
