Answer: C

Solution:

When sound travels in a medium, molecules of medium does not go from one place to another.

The disturbance due to sound is transferred from one molecule to another, hence we can say disturbance travels when sound travels.

In presence of moisture, the speed of sound in air increases. Therefore, sound can certainly travel in moist atmosphere.
