Final answer:
The XYZ Affair led to the Alien and Sedition Acts and increased U.S.-France tensions but did not lead to negotiations with Britain or the Louisiana Purchase, which happened during Jefferson's term.
Step-by-step explanation:
The XYZ Affair was an incident under President John Adams's administration that significantly worsened U.S.-French relations. Outrage caused by French demands for bribes from American negotiators in what became known as the XYZ Affair led directly to a series of actions in the U.S. These actions included the passage of the controversial Alien and Sedition Acts, heightened tensions between the United States and France, and an undeclared naval conflict dubbed the Quasi-War. However, these events did not lead to negotiations for a treaty with Britain, which is a separate historical event from this time. The Louisiana Purchase also did not result from the XYZ Affair; that occurred during Thomas Jefferson's presidency, a few years later.
Therefore, the correct answer is (D) The Louisiana Purchase.
The Louisiana Purchase occurred in 1803, during the presidency of Thomas Jefferson, and is not directly connected to the events following the XYZ Affair, which took place during John Adams's presidency (1797-1801).
