Which of the following is a U.S. territory?

Puerto Rico is recognized as a U.S. territory. This status means that it is under the jurisdiction of the United States, but it does not have the same standing as a state. Residents of Puerto Rico are U.S. citizens, but they do not have voting representation in Congress, and they cannot vote in presidential elections. Understanding territories is important in the context of U.S. governance, as it highlights the differences in rights and representation between states and territories.

In contrast, Hawaii, Florida, and Alaska are all states and have full representation in Congress and the ability for their residents to vote in presidential elections. Recognizing Puerto Rico as a territory emphasizes the diverse status of different regions within the United States and their varying degrees of representation and civil rights.
