The correct option is B Cytochrome c-oxidase
The enzyme cytochrome c-oxidase is a large transmembrane protein complex found in bacteria, archaea, and in eukaryotes in their mitochondria.
It is the last enzyme in the respiratory electron transport chain of cells located in the membrane. It receives an electron from each of four cytochrome-c molecules, and transfers them to one dioxygen molecule, converting the molecular oxygen to two molecules of water. In this process it binds four protons from the inner aqueous phase to make two water molecules, and translocates another four protons across the membrane, increasing the transmembrane difference of proton electrochemical potential which the ATP synthase then uses to synthesize ATP.
Hence, the correct answer is 'Cytochrome c-oxidase'.
