Answer 1

Water from a tap is allowed to fall in a vessel with a thin neck. The pitch of sound produced by falling water increases with the volume of water in the vessel.

Explanation:

As the water level rises, the length of the air column in the neck decreases. Its frequency and pitch increase, so the other options are incorrect.
