Among the statements(a)-(d) the incorrect ones are :
(a) Octahedral CO(III) complexes with strong fields ligands have very high magnetic moments.
(b) When $$\Delta $$₀ < P, the d-electron configuration of Co(III) in an octahedral complex is $$t_{eg}^4e_g^2$$
(c) Wavelength of light absorbed by [Co(en)₃]³⁺ is lower than that of [CoF₆]^3-
(d) If the $$\Delta $$₀ for an octahedral complex of CO(III) is 18,000 cm^-1, the $$\Delta $$_t for its tetrahedral complex with the same ligand be 16,000 cm^-1
