Solution

The correct option is D Proton gradient
The function of the electron transport chain is to produce a transmembrane proton electrochemical gradient as a result of the redox reactions which drives the synthesis of ATP and the last electron acceptor in aerobic respiration is oxygen that is why the requirement of oxygen is there.
So the correct option is 'Proton gradient'.
