$\begin{array}{*{20}{c}} A \\ {{\text{(simplest optically active alkene)}}} \end{array}\,\xrightarrow[{(ii)\,{X_2}/\Delta }]{{(i)\,{H_2}/Ni/\Delta }}$
$ NH_3(g) \rightleftharpoons \frac{1}{2}\,{N_2}\left( g \right) + \frac{3}{2}{H_2}\left( g \right);\,{K_2}$
$\frac{1}{2}\,{N_2}\left( g \right) + \frac{3}{2}{H_2}\left( g \right) \rightleftharpoons NH_3(g); K_3$
$2NH_3(g) \rightleftharpoons N_2(g) + 3H_2(g); K_4$
If $K_1 = K_2^x = K_3^y = K_4^z$ then correct values of $x, y$ and $z$ are respectively
