$2NO(g) + 2{H_2}(g) \to {N_2}(g) + 2{H_2}O(g)$ is :
Step $1$ : $2NO(g) + {H_2}(g)\xrightarrow{{slow}}{N_2} + {H_2}{O_2}$
Step : $2$ ${H_2}{O_2} + {H_2}\xrightarrow{{fast}}2{H_2}O$
Then the correct statement is

$\begin{matrix}
\begin{matrix}
C{{H}_{3}}\,\,\,\,\,\,\,\, \,\, \\
|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\
\end{matrix} \\
C{{H}_{3}}-C-CH=C{{H}_{2}} \\
|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, \\
C{{H}_{3}}\,\,\,\,\,\,\,\, \,\,\,\, \\
\end{matrix}\,$ $\xrightarrow{{{H}_{2}}O/{{H}^{\oplus }}}$ $\underset{Major\,\,product}{\mathop{A}}\,$ $+$ $\underset{Major\,\,product}{\mathop{B}}\,$
The major product is
