Detailed Solution

The given statement is true.
Concept: These three instruments' vibrating components are all made of elastic materials. And for sound to travel, a medium like air, water, etc. is required. Sound is transferred as a result of particle vibration.
Sound is created when an environment is disturbed. Pressure is transferred by compression and rarefaction, which causes vibrations that produce sound.
1) A stretched membrane makes up the vibrating portion of a dholak.
The stretch membrane begins to gently vibrate when the head is struck. The result of this vibration is sound.
2) Stretched strings are what make a sitar vibrate
Stretched string vibrates, which results in sound.
3) The air column inside a flute is what causes it to vibrate.
The air inside the pipe vibrates when air is blown through it, creating sound.
Hence, the given statement is true.
