In the given question, a statement of Assertion is followed by a statement of Reason. Mark the correct answer.

Assertion: The Berlin Wall that separated Western and Eastern Germany was toppled by the governments of East and West Germany in 1989 for the unification of these countries.
Reasoning: This wall was the symbol of the height of the Cold War that created the Western and Eastern alliance in Europe.

The assertion is incorrect but the reason is correct

The Berlin Wall, which had been built at the height of the Cold War and was its greatest symbol, was toppled by the people in 1989. This dramatic event was followed by an equally dramatic and historic chain of events that led to the collapse of the ‘second world’ and the end of the Cold War. Germany, divided after the Second World War, was unified. One after another, the eight East European countries that were part of the Soviet bloc replaced their communist governments in response to mass demonstrations. The Soviet Union stood by as the Cold War began to end, not by military means but as a result of mass actions by ordinary men and women. Eventually the Soviet Union itself disintegrated.
