In the catalytic cycle of Cytochrome $\mathrm{P_{450}}$, the generation of $[(\mathrm{porphyrin})+\mathrm{Fe^{IV}}(\mathrm{O})]$ from $[(\mathrm{porphyrin})\mathrm{Fe^{III}}(\mathrm{OOH})]$ involves
(a)One electron oxidation of $[(\mathrm{porphyrin})\mathrm{Fe^{III}}(\mathrm{OOH})]$
(b)Formation of the intermediate $[(\mathrm{porphyrin})\mathrm{Fe^{IV}}(\mathrm{OH})]$
(c)Homolytic O-O cleavage of $[(\mathrm{porphyrin})\mathrm{Fe^{IV}}(\mathrm{OOH})]$
(d)Heterolytic O-O cleavage of $[(\mathrm{porphyrin})\mathrm{Fe^{III}}(\mathrm{OOH})]$
