The correct answer is B) Berlin.
After World War II, the United States, Soviet Union, France, and Britain split up control of Berlin. The reasoning behind this was to ensure that Nazism was not able to rise again in this country, considering that when it did it helped lead to WWII. However, this joint control of Berlin would become controversial thanks to the rivalry between the US and Soviet Union after World War II. This city became a symbol of division between capitalism and communism and lead to the creation of the Berlin Wall.
