• D. All of the above

Answer 1

The correct option is A Body of whistle

A body of whistle is responsible for the whistle to produce sound.

As air enters the whistle at one end.As the air reaches the other, closed end, all the air molecules fill up on top of each other and cause a high pressure region.The air escapes out the little hole in the end making a sound you hear.The frequency of sound depends on the length of the whistle.
