The velocity of sound in dry air is V(d)...

The velocity of sound in dry air is `V_(d)`, and in moist air it is `V_(m)`. The velocities are measured under the same conditions of temperature and pressure. Which of the following statements is fully correct?

A

`V_(d)gtV_(m)` because dry air has lower density than moist air.

B

`V_(d)ltV_(m)` because moist air has lower density than dry air.

C

`V_(d) gt V_(m)` because the bulk modulus of dry air is greater than that of moist air.

D

`V_(d) lt V_(m)` because the bulk modulus of moist air is greater than that of dry air.
