Which of the following states was acquired as part of the Mexican Cession during the Mexican War?

• A. Arizona
• B. New Jersey
• C. Vermont
• D. North Dakota

Answer: (A)

The land that became part of the Mexican Cession came from the Treaty of Guadalupe Hidalgo in 1848, after the Mexican-American War. This agreement transferred a large southwestern area to the United States, including present-day California, Nevada, Utah, most of Arizona, and parts of Colorado and New Mexico. That’s why Arizona fits the description: it was among the territories ceded by Mexico.

New Jersey and Vermont are in the eastern United States and were never part of this transfer. North Dakota sits far to the north and west and was acquired earlier through other purchases and settlements, not from the Mexican Cession.
