Final Answer :
B
Explanation :
Without oxygen, the body relies on glycolysis to produce energy. Glycolysis involves the breakdown of glucose into pyruvate, which can then be converted into energy in the absence of oxygen. This process can sustain exercise for a short period of time, usually around 90-120 seconds. Therefore, the correct answer is B)glycolysis.
