what country provided critical support to the cuban people in their fight for independence from…

Brief Explanations:

During the Cuban fight for independence from Spain, the United States played a significant role. The U.S. had economic interests in Cuba and was involved in the Spanish - American War. The war led to the Treaty of Paris (1898), which ended Spanish colonial rule in Cuba. While other countries like France and Portugal had their own colonial histories, they were not the main providers of critical support in this context. Jamaica was a British colony at the time and not in a position to provide such support.

C. United States
