The correct answer is A. A wall that separated East and West Berlin

Explanation:

The Berlin Wall was a structure constructed as a barrier that divided Berlin from 1961 to 1989 and separated the East from the West of the city. This wall was constructed because after the World War II Germany and Berlin were ideologically divided, the east of Berlin was controlled by the Soviets and followed the communism ideology while the west Berlin was controlled by the U.S., Great Britan, and France following a democratic system, these ideologies were opposite and because of this and to avoid people from the other side trying to attack the opposite ideology  the bloc of the East constructed the wall, which means people could not cross to the other side of the city. This lasted until 1989 by the end of the cold war when citizens were finally allowed to cross to the other side without restrictions. Thus, the Berlin Wall separated East Berlin support by the communist ideology from West Berlin support by the allies and the democracy.
