The correct answer is:

A. oxygen

Explanation:

In aerobic cellular respiration, oxygen is the final electron acceptor at the end of the electron transport chain. Electrons are passed through a series of protein complexes in the inner mitochondrial membrane, and at the end of the chain, oxygen accepts these electrons and combines with protons (H $+^+$ ) to form water (H $_2$ O). This is crucial for maintaining the flow of electrons through the electron transport chain.
