The following data was obtained for chemical reaction given below at 975 K .
$ \begin{aligned} & 2 \mathrm{NO}_{(\mathrm{g})}+2 \mathrm{H}_{2(\mathrm{~g})} \rightarrow \mathrm{N}_{2(\mathrm{~g})}+2 \mathrm{H}_2 \mathrm{O}_{(\mathrm{g})} \\
& {[\mathrm{NO}] \quad\left[\mathrm{H}_2\right]} \\
& \mathrm{mol} \mathrm{~L}^{-1} \quad \mathrm{~mol} \mathrm{~L}^{-1} \quad \text { Rate } \\
& \mathrm{mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}
\end{aligned} $
(A) $8 \times 10^{-5}$ & $8 \times 10^{-5}$ & $7 \times 10^{-9}$ \\
(B) $24 \times 10^{-5}$ & $8 \times 10^{-5}$ & $2.1 \times 10^{-8}$ \\
(C) $24 \times 10^{-5}$ & $32 \times 10^{-5}$ & $8.4 \times 10^{-8}$
The order of the reaction with respect to NO is $\_\_\_\_$ . [Integer answer]
