The correct answer is B. Roosevelt and Churchill agreed to attack Germany on the western front.
At first, they declared that the initial assault would occur in May, but it got moved to June and there we have what is known as Operation Overlord, that is the allied invasion of Normandy. At first, airplanes bombed Germans in Normandy for a while after which a huge force crossed the English channel and they reached what was known as Omaha Beach in 1944.
