Best answer
Correct choice is (c) 36

The explanation: In one cycle of glycolysis, 6 ATP is obtained. Each molecule of glucose gives 2 pyruvate which corresponds to 6 ATP. There is also formation of 2 acetyl-CoA molecules which is about 24 ATP. Thus each molecule of Glucose give 36 ATP. ( Note that about 34 ATP molecules are consumed in glycolysis thus the net yield is 2 ATP).
