The Berlin Wall became a symbol of division in which city?

Correct answer: Berlin

The Berlin Wall was constructed in 1961 and became the most visible symbol of the division of Berlin during the Cold War. It separated West Berlin from East Berlin and represented the wider political, ideological, and military division between the Western bloc and the Soviet-led Eastern bloc. Although the wall was a physical structure, its importance was also symbolic: it showed how international rivalry divided communities and restricted movement. It fell in 1989, becoming a sign that the division was weakening.

Option B is correct because the wall divided Berlin itself. Moscow, Vienna, and Prague were important European cities in Cold War history, but the Berlin Wall was not a structure dividing any of them. The useful memory link is Berlin Wall, divided Berlin, and Cold War. This connection helps distinguish the event from other Cold War tensions and from the later reunification of Germany.
