Solution

The correct option is B Tuning fork
When a tuning fork strikes on a rubber pad , due to the vibrations of arms of fork , a sound is produced .

A simple pendulum is an example of simple harmonic motion .
An oscillator is used to generate required frequencies .

Hence, option A is correct.

Three different vibrating objects produce three types of sounds X, Y and Z. Sounds X and Y cannot be heard by a man having normal range of hearing but sound Z can be heard easily. The sound X is used in hospitals to break kidney stones of a patient into fine grains which then get flushed out with urine. The sound Y is similar to that which is produced during an earthquake before the main shock wave is generated.
