Answer :
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

That is because sound depends on the distance between molecules. Sound in solids travel much faster and easier than in gas.
