Answer 1

The correct option is A Statement 1 is correct whereas statement 2 is incorrect.

Sound is caused due to the vibrations of particles.
For instance, when we strike a plate it produces sound. But on immediately holding it, the vibrations stop so does the sound.
Non-vibrating bodies do not produce sound.
