Solution

The correct option is D $S O_{4}^{2 -}, P O_{4}^{3 -}$
Isoelectronic species have same no. of total electrons.
Out of the given options, only $S O_{4}^{2 -}$ and $P O_{4}^{3 -}$ is the isoelectric pair with $50$ electrons. Also, they have the same tetrahedral geometry, hence they are isostructural as well.
