Question

how did his defeat in russia change napoleons fortunes?
when napoleon lost, the french surrendered to the russians.
because he was captured outside moscow, he was sent into exile.
in addition to losing many of his troops, his empire turned against him.
after he put his brother on the throne, the russian people rose against him.

Explanation:

Napoleon's 1812 Russian campaign saw his Grande Armies decimated by cold, starvation, and Russian tactics. This massive loss of military strength weakened his hold over his empire, leading allied powers and regions under his control to turn against him, ending his dominant position in Europe. The other options are incorrect: France did not surrender immediately, he was not captured/exiled after this defeat, and he did not place his brother on Russia's throne.

Answer:

C. In addition to losing many of his troops, his empire turned against him.
