Coordination Compounds Part 1

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 Δ0<P , the d-electron configuration of Co(III) in an octahedral complex is teg4eg2
(c) Wavelength o f light absorbed by [Co(en)3]3+ is lower than that of [CoF6]3−
(d) If the Δ0 for an octahedral complex of Co(III) is 18,000 cm‌−1 , the At for its tetrahedral complex with the same ligand will be 16,000 cm−1
