Well it depends what the context is. But if you’re talking about the treaty of Versailles, the answer is B (Germany)
The correct answer is the Louisiana Purchase.
While the President has the power to negotiate treaties, Jefferson likely got quite a bit ahead of himself when the land was purchased before the consent of the United States Senate.
Furthermore, the Federalists believed that the acquisition of territory itself might be unconstitutional.
I think the answer would be reassure white american settlers that the frontier was safe and peaceful.
Hope this helps
I think its A. but not so sure
