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

Octahedral $\mathrm{C}\mathrm{o}$ (III) complexes with strong field ligands have very high magnetic moments

When ${\mathrm{\Delta }}_0<\mathrm{P}$ , the d-electron configuration of $\mathrm{C}\mathrm{o}$ (III) in an octahedral complex is ${\mathrm{t}}_{\mathrm{e}\mathrm{g}}^4{\mathrm{e}}_{\mathrm{g}}^2$
Wavelength of light absorbed by ${\left[\mathrm{C}\mathrm{o}(\mathrm{e}\mathrm{n}{)}_3\right]}^{3+}$ is lower than that of ${\left[{\mathrm{C}\mathrm{o}\mathrm{F}}_6\right]}^{3-}$

If the ${\mathrm{\Delta }}_0$ for an octahedral complex of $\mathrm{C}\mathrm{o}$ (III) is $\mathrm{18,000}{\mathrm{c}\mathrm{m}}^{-1}$ , the ${\mathrm{\Delta }}_{\mathrm{t}}$ for its tetrahedral complex with the same ligand will be $\mathrm{16,000}{\mathrm{c}\mathrm{m}}^{-1}$
