The correct answer is D. The coining of the term Iron Curtain is attributed to Winston Churchill. He used this expression in a speech he gave in March 1946 in Fulton, Missouri. The Iron Curtain was the physical boundary dividing Europe into the two separate areas after the World War II, and until the end of the Cold War in 1991, and it symbolized the effort by the Soviet Union to block it self from the Western countries. East from the Iron Curtain were the Soviet Union allies, and on the west were allies of the second world's great superpower - The United States.
