Ans.

The electron transport chain is defined a series made up of electron transporters that transfer electrons to their acceptors from donors. The transfer of electrons is coupled with proton transfer across the membranes of mitochondria, as protons are pumped out from mitochondrial matrix to outside or mitochondrial inter-membrane space.

Thus, the correct answer is 'option b). protons are pumped out of the mitochondria by the complexes of the electron transport chain.'
