Correct:
A
Explanation
The process described — complete oxidation of glucose in the presence of oxygen to form carbon dioxide and water with release of energy — is aerobic respiration. Textual evidence states that some organisms "use oxygen to break-down glucose completely into carbon dioxide and water," and that the oxygen-dependent breakdown of pyruvate occurs in mitochondria, indicating full oxidation under aerobic conditions [1]. The standard word equation for this process is given explicitly as Glucose + Oxygen → Carbon dioxide + Water + Energy, which matches the description in the question [2]. Thus the correct choice naming this complete, oxygen-requiring conversion is aerobic respiration.
