The correct answer is C) three-pronged attack.
To achieve a victory in Europe, the Allies needed to create an effective three-pronged attack.
During World War II, the Allies faced many problems to defeat the strategies of the powerful German Army. That is why they had to use a three-pronged attack, which was the attack of the Allies forces in three different places. There was the European battlefront, the Noth African battlefront to control the Suez canal and stop provisions that the German Army needed so much, and finally, the Pacific front. On December 7, 1941, Japan had attacked the island of Pearl Harbor in Hawaii, where the US had a navy base. That is when the US decided to enter World War II.
