Step-by-step solution
Primary valency = Oxidation state
Secondary valency = Co-ordination number
\begin{array}{|l|l|c|c|}\hline & Complex & \begin{array}{l} \text{Primary} \\ \text{valency}\end{array} & \text{Secondary} \hline (A) & {\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right] \mathrm{Cl}} & 3 & 6 \hline (B) & {\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}\left(\mathrm{NO}_2\right)\right]} & 2 & 4 \hline (C) & \mathrm{Hg}\left[\mathrm{Co}(\mathrm{SCN})_4\right] & 3 & 4 \hline (D) & {[\mathrm{Mg}(\mathrm{EDTA})]^{2-}} & 2 & 6 \hline\end{array}$
Secondary valency = Co-ordination number
