Answer:
The correct answer for this is C, because the Fadh2 is only involved at the redox reactions.
Step-by-step explanation:
ATP is just a product from glycolysis. Remember that when you break the glucose, energy is been free as an ATP molecule. NADH2 is a substratum, you need it, to get NAD at the fermentation process in the cytoplasmic matrix. Pyruvate and phosphoenolpyruvate are also products at the glycolysis.
