The major geographical effect of World War 2 on Germany was:
a) The Soviet zone of occupied Germany became communist East Germany.
After World War 2, Germany was divided into four zones of occupation controlled by the Allied powers - the United States, Great Britain, France, and the Soviet Union. The Soviet zone of occupied Germany eventually became East Germany, which was under Soviet influence and established as a communist state. This division led to the creation of East and West Germany, symbolizing the broader East-West divide of the Cold War era.
