None of the options listed were the reason the United States entered World War I.

The United States entered World War I in April 1917, after Germany resumed unrestricted submarine warfare in the Atlantic Ocean. This policy put American lives and shipping at risk and led to the sinking of several American merchant ships and passenger liners, including the Lusitania. Additionally, Germany's attempts to form a military alliance with Mexico, as revealed in the Zimmermann Telegram, further provoked the United States and contributed to its decision to enter the war.
