Answer:
Option C, is the right answer.
Step-by-step explanation:
The Berlin Airlift begins at the time when the Soviet Union blocked road and rail travel into West Berlin. This blockade was enacted by the Soviet Union in response to the refusal of the U.S. and Britain to provide Russia more say in the economy of Germany. To break the blockade, President Truman could not take direct military action as it could cause World War III, so he ordered a massive airlift of necessary goods into West Berlin. The successful U.S. airlift led the Soviet Union to end the blockade. The end of the blockade led Germany to become a separate and independent nation. The effect can be seen in the fact that West Berlin was regarded as the Island of Freedom throughout the Cold War.
