$M + L \rightleftharpoons ML$
$ML + L \rightleftharpoons M{L_2}$
are $4$ and $3$. Hence, overall stability constant for
$M + 2L \rightleftharpoons M{L_2}$ is
Set $1$: $Al_2O_3 .xH_2O\, (s)$ and $OH^-(aq)$
Set $2$: $Al_2O_3 .xH_2O\, (s)$ and $H_2O\,(l)$
Set $3$: $Al_2O_3 .xH_2O\, (s)$ and $H^+(aq)$
Set $4$: $Al_2O_3 .xH_2O\, (s)$ and $NH_3(aq)$
