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

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

(b) When $\Delta_{0}

(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 $18,000 \mathrm{~cm}^{-1}$, the $\Delta_{t}$ for its tetrahedral complex with the same ligand will be 16,000 $\mathrm{cm}^{-1}$
