Answer:
C. Native Americans allies of France.
Explanation:
The Treaty of Paris of 1763 put an end to the conflict between France and Britain during the French-Indian War. This conflict resulted in a British victory.
The French were allied with the Native Americans, who wanted to keep their lands west of the Appalachians, in what is now the Ohio River and the Great Lakes States.
The war broke out because American frontier colonists of British origin were pushing eastwards, and creeping into these Native American Lands.
We can see then, that the Native Americans were tyring to protect their lands, and the terms of treaty, which gave the obvious advantage to Britain, the victor of the war, represented a great loss of power to them.
