The correct answer is A. The oxygen molecule accepts electrons from a compound called cytochrome a3. Cytochromes contain a central Iron atom that can either be in the oxidised state(ferric state) Fe3+ or reduced state(ferris state) Fe2+. The cytochrome is oxidized by giving the electron to O2(O2 is reduced).O2 becomes 2O- that quickly react with H+ to form H2O.
