Answer
Answer:
B. Iron Curtain
Brief Explanation:
The Iron Curtain was a political - ideological boundary in Europe during the Cold War. When Hungary opened its borders in 1989, it was seen as creating a "hole" in this symbolic barrier that separated the Western and Eastern blocs. The Berlin Wall was a physical structure in Berlin, and the other options are not relevant in this context.
