Answer the following question given this paragraph: 

Then, about 2 or 3 billion years ago, oxygen was gradually added to the atmosphere by early photosynthetic bacteria. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration .

 Choices:

- digestive respiration

- anaerobic respiration

- kinetic respiration

- aerobic respiration

A:
aerobic respiration
