A Correct answer
Explanation

Anaerobic respiration (glycolysis) yields a net gain of only 2 ATP per glucose molecule. This occurs in the cytoplasm when oxygen is absent. Aerobic respiration produces 36-38 ATP through complete glucose oxidation in mitochondria. The options of 3, 10, or 38 ATP do not match the known yield of anaerobic glycolysis.
