Which two states border Oklahoma to the south?

The correct answer is Texas and Arkansas. Oklahoma shares a southern border exclusively with Texas, which is the only state directly adjacent to Oklahoma in that direction. Additionally, Arkansas lies directly to the southeast of Oklahoma, creating a natural boundary between the two states. This geographical relationship is significant in understanding the regional dynamics and historical interactions between these states, including trade, migration patterns, and cultural exchanges.

While other options may include states that are geographically near Oklahoma, they do not accurately represent the states that share a southern border. Louisiana is located further southeast and does not share a border with Oklahoma. Similarly, Missouri, although bordering Oklahoma to the north and east, and Mississippi, which is a separate state to the east of Louisiana, do not fit the criteria for neighboring states to the south. Understanding Oklahoma's borders helps in comprehending its historical context and relationships with neighboring states.
