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

(a) Octahedral \( \mathrm{Co} \) (III) complexes with strong field ligands have very high magnetic moments

(b) When \( \Delta_{0}< \) P, the d-electron configuration of \( \mathrm{Co} \) (III) in an
octahedral complex is \( \mathrm{t}_{2 \mathrm{g}}^{4} \mathrm{e}_{g}^{2} \)

(c) Wavelength of light absorbed by \( \left[\mathrm{Co}(\mathrm{en})_{3}\right]^{3+} \) is lower than that of \(
\left[\mathrm{CoF}_{6}\right]^{3-} \)

(d) If the \( \Delta_{0} \) for an octahedral complex of \( \mathrm{Co} \) (III) is 18,000 \( \mathrm{cm}^{-1} \) \( \Delta_{t} \) for its tetrahedral complex with the same ligand will be \( 16,000 \mathrm{~cm}^{-1} \)
