Solution

The correct option is D
Water surface starts vibrating

When a vibrating body is touched to another body, the vibrations of the first body get transmitted to the second body. Therefore, when the vibrating tuning fork is touched to the water surface, the vibrations of the fork get transmitted to the water, causing the water surface to start vibrating.
