Solution
The correct option is B solid > liquid > gas
As the molecules are more close in solid so that the vibration moves fast and hence speed of the sound is fast in solid. In the similar way in liquid, molecules are less close and in gases, the molecules are least close. Hence speed of sound is in the order of solid> liquid> gas
