Solution

The correct option is B Iron
Cytochromes are iron containing protein. It helps in the generation of ATP by electron transport chain. It helps in the transfer of electrons by oxidation and reduction. The iron present in the cytochrome gets converted into Fe2+ into Fe3+. It also transfers electrons between complex III and complex IV during electron transport chain.
So, the correct answer is option C.
