(C) The formula for root mean square velocity $(V_{rms})$ is given by: $V_{rms} = \sqrt{\frac{3RT}{M}}$ where $R$ is the universal gas constant,$T$ is the temperature,and $M$ is the molar mass (or $m$ as the molecular mass). From the expression,it is clear that $V_{rms} \propto \frac{1}{\sqrt{m}}$,which can be written as $V_{rms} \propto m^{-1/2}$.
