6. The Fe=O oxidizing center in cytochrome P-450 is characterized as an Fe(IV) complex with the porphyrin also oxidized by one electron. Which of the following statement is      incorrect     ?
(A) The complex has a magnetic susceptibility that indicates the presence of two unpaired electrons
(B) The iron ion is in a triplet state (S = 1)
(C) The Fe(IV) oxidation state corresponds to t_2g⁴ with two unpaired electrons
(D) The oxidation of the porphyrin ring removes one electron from the π HOMO
(E) Cytochrome P-450 is the enzyme with iron porphyrin active site that catalyzes the addition of oxygen to a substrate
