C.
Anaerobic respiration (fermentation) yields far fewer ATP per glucose molecule (about 2 ATP) than aerobic respiration (~30–38 ATP), so it is less energy-efficient. Options A, B and D are incorrect: anaerobic needs no oxygen (so it doesn't require more), and it produces products like lactic acid (in animals) or ethanol + CO2 (in yeast), not less lactic acid than aerobic.
