Correct Answer: Option B

Explanation

The speed of sound depends on the density of the medium in which it travels and increases when the density increases. For example, in solids sound travels faster than in liquid and even faster than in gas, and the density is highest in solids, lower in liquids, and lowest in gas. Hence, sound travels fastest in solids.
