Name one U.S. territory.

Puerto Rico is a U.S. territory, which means it is an area under the jurisdiction of the United States but not a state. It has its own local government but its residents are U.S. citizens. This distinguishes it from other choices provided.

The Canadian Territories do not pertain to U.S. territories as they are part of Canada, and Papua New Guinea is an independent country located in Oceania. Similarly, the British Virgin Islands are a British Overseas Territory and not under U.S. jurisdiction. Therefore, Puerto Rico stands out as the correct answer for a U.S. territory.
