Which is not an American state?

This question tests geographical knowledge, specifically distinguishing between states of the United States and other sovereign nations or regions in the Americas. Canada is a large country located in North America, bordering the United States, but it is not one of the 50 states of the USA. Therefore, it is the correct answer.

• Paraguay is a sovereign country in South America, not a state of the USA.
• Alaska is the largest state by area in the United States, located in the northwest extremity of North America.
• Texas is the second-largest state by both area and population in the United States, located in the south-central region.

The distractors B and D are actual American states, while A and C are countries, with C being the designated correct answer for "not an American state" in the context of US states.
