Match Column $\mathrm{l}$ and Column $\mathrm{ll}$ and choose the correct option using the codes given below:

A metal ion ${\mathrm{M}}^{\mathrm{n}+}$ having ${\mathrm{d}}_4$ valence electronic configuration combines with three bidentate ligands to form a octahedral complex compound. Assuming ${∆}_{\mathrm{o}}>\mathrm{P}$. Write the electronic configuration of the valence electrons of the metal ${\mathrm{M}}^{\mathrm{n}+ }$ion in terms of ${\mathrm{t}}_{2\mathrm{g}}$ and $\mathrm{eg}$ .
 

A metal ion ${\mathrm{M}}^{\mathrm{n}+}$ having ${\mathrm{d}}^4$ valence electronic configuration combines with three bidentate ligands to form an octahedral complex compound. Assuming ${∆}_{\mathrm{o}}>\mathrm{P}$, what type of hybridisation will ${\mathrm{M}}^{\mathrm{n}+}$ ion have?
