The correct answer is D. In the Adams-Onis Treaty, Spain gave up all clams to land north of the 42nd parallel.
Explanation:
The Adams-Onis Treaty was the result of the negotiation between Spain and the United States to fix the border between the American nation and the then viceroyalty of New Spain.
The border was set beyond the Sabine River and Arkansas to the 42nd parallel north. As a result, Spain renounced its possessions beyond that latitude, including the territory of Oregon. It also ceded definitively the Floridas, Louisiana and the navigation by the Mississippi river. The Spanish Crown remained the sole sovereign of Texas, territory that the United States claimed as part of Louisiana, which was purchased from the French in 1803.
