c) Coal

During the Berlin Airlift, coal was the main item flown into Berlin to alleviate the blockade imposed by the Soviet Union. From 1948 to 1949, Western Allies organized a massive airlift to provide essential supplies to West Berliners, who were cut off from the rest of West Germany. Coal was crucial for heating and power generation, especially during the harsh winter months. The Berlin Airlift was a significant Cold War event, symbolizing the commitment of the Western Allies to support West Berlin in the face of Soviet aggression.
