After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?

A
Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.
B
Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.
C
Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
D
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
