It's the third one, this treaty is also knows as the Florida Purchase Treaty, try to remember it as that, and you'll always know the answer to questions about it:)) i hope this helped!
The correct answer is the third. The Adams-Onis Treaty was the result of the negotiation between Spain and the United States to fix the border between the North American nation and the viceroyalty of New Spain.
The border was set beyond the Sabina River and Arkansas. As a result, Spain renounced to its possessions beyond that territory, including Oregon. Spain also ceded definitively Florida and Louisiana.
