In Battle of the Bulge Nazis broke through the Western front through Berlin Walls on the Soviets.

Option C

Explanation:

During World war II, Nazis decided to create a bulge around the Ardennes forest area on Western front. It was the weak and very poorly protected 80 mile area and therefore it was called as the battle of bulge.

One more trick used by Germans were to send English speaking German officials and trick the Americans and take all the jeeps, uniforms, trucks etc. This war resulted into great loss of American civilian life and ended when the weather was right for American aircrafts to launch bombs.
