Answer
Answer:
A. Napoleon's empire turned against him.
Brief Explanations:
After France's defeat in Russia, Napoleon's losses were massive. His empire's states, seeing his weakened position, began to turn against him (e.g., Prussia, Austria re - entered the war against him). The other options are incorrect: Napoleon didn't escape to America; the French people's support wasn't the main reason for the turning point here; and the French army was severely weakened, not reinvigorated, by the Russian campaign.
