$\displaystyle \mathrm{C}_p$ and $\displaystyle \mathrm{C}_v$ are specific heats at constant pressure and constant volume respectively. It is observed that
$$\begin{aligned}
& C_p-C_v=a \text { for hydrogen gas } \\
& C_p-C_v=b \text { for nitrogen gas }
\end{aligned}
$$
The correct relation between a and b is :
Official answer
(3)
$\displaystyle a=14 \mathrm{~b}$
