B. The war resulted in expanded British and Spanish territory at the expense of France.
Explanation:
France lost practically all of their territories following their debacle in the French and Indian War to Great Britain and Spain, though later on Spain will return the Louisiana Territory to France. France, on return would then sell the Louisiana to the growing US.
Also, the French and Indian War only came at the expense of the mainland American territories held by France. France still had holdings in other regions in the Americas.
