Which event led to the U. S. officially joining World War II in 1941? Zimmerman telegram
attack on Pearl Harbor
sinking of the Lusitania
Germany invading Poland

B attack on Pearl Harbor

Explanation:

the Zimmerman Telegram was when the German Empire sent a telegram made by Zimmerman to Mexico to try and get them to fight the USA to keep them from joining the Entante, that was WW1 so it's unrelated to ww2.
