Question

at the tehran conference, the big three agreed on which overriding goal?
the need to bring a halt to the fighting
the need to invade the italian peninsula
the need to open a second front against germany
the need to invite hitler to future conferences

Explanation:

The Tehran Conference (1943) involved the "Big Three" (Roosevelt, Churchill, Stalin). Their key agreement was on opening a second front against Germany (via the planned Normandy invasion, though the plan was solidified in terms of the need for a second front). The other options: halting fighting was not the overriding goal here, invading Italy was already in progress, and inviting Hitler is illogical.

Answer:

C. the need to open a second front against Germany
