$\left[\mathrm{Pt}\left(\mathrm{Ox}\right)(\text{ py }{)}_2\left({\mathrm{O}}_2\right)\left({\mathrm{H}}_2\mathrm{O}\right)\right]$ Select correct statement about this complex :

The nearest inert gas of Pt is Rn, the total electrons in Rn is 86. By calculating the EAN of Pt in the complex, $\left[\mathrm{Pt}\left(\mathrm{ox}\right)\left({\mathrm{py}}_2\right)\left({\mathrm{O}}_2\right)\left({\mathrm{H}}_2\mathrm{O}\right)\right]$. EAN $=\mathrm{Z}-\mathrm{ON}+(2\times \mathrm{L})$ Where, Z is atomic number, ON is oxidation state on central metal, and L is ligand.

$\begin{array}{l}\mathrm{Pt}=\mathrm{Z}-\mathrm{ON}+(2\times \mathrm{L})\\ =78-4+(2\times 6)\\ =86\end{array}$Ox is a bidentate complex with an octahedral structure in this complex. So there are two types of geometrical isomerism possible here: cis and trans. It may also exhibit optical isomerism due to its less symmetric nature.

So, option D is correct.
