You haven't provided me with any pathways to choose from! Please provide the list of pathways so I can help you determine which produces the most NADH and least ATP.

For example, you could say:

"Which of the following pathways produces most NADH and least ATP: glycolysis, the citric acid cycle, or the electron transport chain?"

Once you provide the pathways, I'll be happy to explain which one produces the most NADH and least ATP.
