(C) We know that for an ideal gas,the Mayer's relation is given by $C_P - C_V = R$.Dividing both sides by $C_V$,we get $\frac{C_P}{C_V} - 1 = \frac{R}{C_V}$.Given that $\gamma = \frac{C_P}{C_V} = \frac{9}{7}$.Substituting the value of $\gamma$ into the equation,we get $\frac{R}{C_V} = \gamma - 1$.$\frac{R}{C_V} = \frac{9}{7} - 1 = \frac{9-7}{7} = \frac{2}{7}$.Calculating the decimal value,$\frac{2}{7} \approx 0.2857$.Thus,the value is nearly $0.28$.

For an ideal non-rigid diatomic gas,the value of $\frac{R}{C_V}$ is nearly,given that $\gamma = \frac{C_P}{C_V} = \frac{9}{7}$.
