Detailed Solution

Statement I:[Mn(CN)₆]^3–, [Fe(CN)₆]^3– and[Co(C₂O₄)₃]^3– and d²sp³hybridized due to strong field ligand involve inner d-orbital.
Statement II: [MnCl₆]^3–and [FeF₆]^3– are paramagnetic and have 4 and 5 unpaired electrons, respectively because ${Mn}^{+ 2}$ has $t_{2 g}^{3} e_{g}^{1}$ and $t_{2 g}^{3} e_{g}^{2}$ .
