Respuesta :
A. Puerto Rico was acquired after the Spanish-American War.
The right answer is A. Puerto Rico. The size of Puerto Rico is 9104 Km^{2}. With the Treaty of Paris signed in 1898 Spain renounced all claim to Cuba and ceded Guam and Puerto Rico. Guam is a very small island in the Pacific Ocean. With this war the United States emerged as a world power with far-flung overseas possessions and a position in international politics.
