Among the statements (a)-(d), the incorrect ones are :

Octahedral Co(III) complexes with strong field ligands have very high magnetic moments

When $\displaystyle \Delta_0<\mathrm{P}$, the d-electron configuration of Co(III) in an octahedral complex is $\displaystyle \mathrm{t}_{\mathrm{eg}}^4 \mathrm{e}_{\mathrm{g}}^2$

Wavelength of light absorbed by $\displaystyle \left[\mathrm{Co}(\mathrm{en})_3\right]^{3+}$ is lower than that of $\displaystyle \left[\mathrm{CoF}_6\right]^{3-}$

If the $\displaystyle \Delta_0$ for an octahedral complex of $\displaystyle \operatorname{Co}$ (III) is $\displaystyle 18,000 \mathrm{~cm}^{-1}$, the $\displaystyle \Delta_{\mathrm{t}}$ for its tetrahedral complex with the same ligand will be $\displaystyle 16,000 \mathrm{~cm}^{-1}$
