a) XYZ Affair

Explanation:

The XYZ case was a diplomatic episode that worsened relations between France and the United States and led to the undeclared Quasi-War of 1798. The Jay Treaty of 1795 angered France, which was at war with Britain and interpreted the treaty as evidence of an alliance between Great Britain and the United States. President John Adams and his Federalist Party had also been critical of the tyranny and extreme radicalism of the French Revolution, further worsening relations between France and the United States.
