d. 1919

Explanation:

World War I began in 1914, but the United States initially remained neutral. In 1917, due to factors like the Zimmermann Telegram and unrestricted submarine warfare by Germany, the US declared war on Germany and entered World War I. Option a (1914) is when the war started in Europe, option c (1918) is during the later stages of the war, and option d (1919) is when the war had already ended with the Treaty of Versailles. So the correct option is b.

Answer:

b. 1917
