Which treaty followed the Paris Peace Conference to formally end WWI?

The Treaty of Versailles is the correct answer as it was specifically designed to formally end World War I and outline the terms for peace between the Allies and Germany. Signed on June 28, 1919, the Treaty is named after the location where it was negotiated and signed, near Paris. It not only established significant territorial changes and reparations that Germany was required to pay but also laid the groundwork for the establishment of the League of Nations, an international organization aimed at promoting peace and cooperation among countries.

In contrast, the other treaties mentioned serve different historical contexts. The Treaty of Paris is associated with the end of the American Revolutionary War, while the Treaty of Ghent concluded the War of 1812 between the United States and Great Britain. The Treaty of Trianon, on the other hand, was signed in 1920 and dealt with the end of hostilities between the Allied Powers and Hungary, thus it is not directly related to the conclusion of World War I but rather to the ramifications that arose post-war.
