Answer :
Final answer:
The Zimmermann Telegram played a significant role in prompting the United States to enter World War I, as it proposed a German-Mexican alliance against the United States, exacerbating existing tensions. Therefore correct option is B
Explanation:
Furor over the Zimmermann Telegram contributed greatly to the US entering World War I. The British intercepted a secret message from the German Foreign Minister, Arthur Zimmermann, to their ambassador in Mexico, proposing that if the United States declared war on Germany, Mexico should join the Germans. In exchange for their support, Germany promised to help Mexico recover territories lost to the US, namely Arizona, New Mexico, and Texas. The revelation of this alliance proposal, combined with Germany's unrestricted submarine warfare and the sinking of American ships, made a powerful argument for the United States to declare war on Germany, which they eventually did on April 6, 1917.
