Why does aerobic respiration produce more atp than anaerobic respiration?

Aerobic respiration produces more ATP than anaerobic respiration because aerobic respiration occurs when oxygen is present and is then able to produce ATP as normal with a profit. However, anaerobic respiration has a lack of oxygen, which leads to either fertilization, only producing enough ATP to keep the cycle going and the cell surviving, (not creating any excess/profit ATP).

Ithink the answer is d.
