The following statements are made regarding electron transport chain and oxidative phosphorylation:

A. Complex I (NADH: ubiquinone oxidoreductase) transfers electrons from NADH to oxygen.

B. Complex II (succinate dehydrogenase) transfers electrons from succinate to ubiquinone (Coenzyme Q).

C. The flow of electrons through Complex III pumps protons into the mitochondrial matrix.

D. Complex IV (cytochrome c oxidase) catalyzes the transfer of electrons from cytochrome c to molecular oxygen.

E. ATP synthase uses the proton gradient across the inner mitochondrial membrane to drive the synthesis of ATP from ADP and inorganic phosphate (Pi).

Which one of the following options represents the combination of all correct statements?
