The correct answer is A. This statement refers to the beginning of the Cold War.
Explanation:
The Iron Curtain was a term used for ideological and often material borders that divided Europe in two parts from the end of World War II in 1945 to about 1991. The term became known after Winston Churchill used it in the "Iron Curtain Speech" on March 5, 1946.
The Iron Curtain divided Europe into "Eastern Europe", which was formed by the Soviet Union and other Warsaw Pact countries, and "Western Europe" which was formed by the European countries that were NATO members. The term "Central Europe" almost disappeared from the debate at the same time. It was one of the first divisions that appeared in the world as a result of the Cold War.
