The correct answer is C. By the end of 1944, during the last days of Nazi Germany, Allied forces had blocked Germany on three sides.
On the one hand, on the Eastern Front, the Soviet Union had defeated the Axis in Stalingrad, forcing its withdrawal to Germany and advancing to Hungary, liberating countries in the Baltic, the Balkans and Eastern Europe.
In turn, the American and British forces and their allies liberated France, beginning to encircle Germany on the Western front.
And in turn, the Americans had also liberated Italy, closing the German territory from the south.
