Which of the following best explains why aerobic respiration is more energy efficient than anaerobic respiration?

You haven't added any of your own reasons, but let me give you some of my own that I happen to know on the top of my head:

- Anaerobic oxygen uses lactic acid instead of oxygen, tiring your muscles out, also causing heavy breathing, which is called an 'oxygen debt'.

- Aerobic Respiration the appropriate amount of energy required, ( I think?)

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
