(B) The ratio of specific heats is given by $\gamma = \frac{C_p}{C_v} = 1 + \frac{2}{f}$,where $f$ is the total number of degrees of freedom.Given $\gamma = \frac{9}{7}$,we have $\frac{9}{7} = 1 + \frac{2}{f}$.Subtracting $1$ from both sides,we get $\frac{2}{7} = \frac{2}{f}$,which implies $f = 7$.However,the question specifically asks for the degrees of freedom for translational motion.For any gas molecule,the number of degrees of freedom for translational motion is always $3$ (along the $x, y,$ and $z$ axes),regardless of the total degrees of freedom.

The ratio of specific heats of a gas is $\frac{9}{7}$. The number of degrees of freedom of the gas molecules for translational motion is:
