Explanation:

• Option A: The Zimmermann Telegram (Germany's attempt to get Mexico to join the war against the US) outraged Americans and was a key factor.
• Option B: German unrestricted submarine warfare (attacks on merchant/passenger ships, like the Lusitania) led to US casualties and anger, pushing towards war.
• Option C: American troops arriving in Europe was a result of the US declaring war, not a cause.
• Option D: The Russian Revolution (overthrowing the tsar) didn't directly contribute to the US declaring war; it affected the war's dynamics later but not the US entry.

Answer:

A. Germany's attempt to convince Mexico to join the war, B. German attacks on merchant and passenger ships
