Explanation:

The Zimmermann Telegram, which proposed a military alliance between Germany and Mexico against the US, and Germany's resumption of unrestricted submarine warfare, which endangered American lives and trade, were key factors that directly led the US to enter World War I in 1917. The Treaty of Versailles was signed after the war in 1919. The German invasion of Belgium was an early - war event in 1914 and was more of a factor in drawing other European powers into the war. The Russian Revolution in 1917 mainly affected Russia's role in the war and its internal situation rather than directly causing the US to enter the war.

Answer:

D. The Zimmermann Telegram and unrestricted submarine warfare
