Solution

The correct option is D
We know that the velocity of sound in a gas is given by,

V=γRTM

where γ is the adiabatic index, R is universal gas constant, T is absolute temperature and M is molecular mass of the gas.

At constant temperature, we can see that the velocity is independent of pressure variation.

Hence, velocity of sound will remain constant as pressure changes.

So, option (d) is correct.
