the answer is B.) Cuba

B. Cuba

Explanation:

Although Spain lost all of their colonies on the mainland by 1825, it retained control over Cuba and Puerto Rico. It had already lost control of Hispaniola due to uprisings by enslaved people in Haiti. In Cuba, Spanish forces put down several major rebellions, including one which lasted from 1868 to 1878.
