At a given temperature if `V_(rms)` is the root mean square velocity of the molecules of a gas and `V_(s)` be the velocity of sound in it, then these are related as `(gamma=(C_(p))/(C_(v)))`
A. `v_(rms)=v_(s)`
B. `v_(rms)=sqrt((3)/(gamma))xxv_(s)`
C. `v_(rms)=sqrt((gamma)/(3))xxv_(s)`
D. `v_(rms)=((3)/(gamma))xxv_(s)`
