Answer

Correct option: C.
Solid
Sound is produced due to the vibration of different objects. Sound travels as a longitudinal wave through a material medium. Sound travels as successive compressions and rarefactions in the medium. Sound requires a medium to travel. It travels the fastest in a solid medium because the particles in a solid medium are closely placed as compared to liquids and gases.
