| List-I | List-II |
|---|---|
| (I) $\left[\mathrm{Cr}(\mathrm{CN})_{6}\right]^{4-}$ | (P) $t_{2 \mathrm{g}}$ orbitals contain 4 electrons |
| (II) $\left[\mathrm{RuCl}_{6}\right]^{2-}$ | (Q) $\mu$ (spin-only $)=4.9 \mathrm{BM}$ |
| (III) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}$ | (R) low spin complex ion |
| (IV) $\left[\mathrm{Fe}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}$ | (S) metal ion in $4+$ oxidation state |
| (T) $d^{4}$ species |
[Given: Atomic number of $\mathrm{Cr}=24, \mathrm{Ru}=44, \mathrm{Fe}=26$ ]
Match each metal species in LIST-I with their properties in LIST-II, and choose the correct option
