The answer is West Berlin.
East Germany was already under Soviet control after World War II, as it was part of the Eastern Bloc. The Berlin blockade was not intended to bring East Germany under Soviet control, as it was already within their sphere of influence.
West Berlin was the target of the Berlin blockade. The Soviet Union aimed to force the Western Allies (the United States, the United Kingdom, and France) out of West Berlin by cutting off all land and rail access to the city. The goal was to bring West Berlin under Soviet control or at least to make it dependent on the Soviet Union for supplies.
West Germany was not directly targeted by the Berlin blockade. The blockade was specifically focused on West Berlin, although it did have implications for West Germany as a whole, as it was part of the broader context of Cold War tensions between the East and the West.
East Berlin was already under Soviet control, as it was the eastern part of the city and the capital of East Germany. The blockade was not intended to bring East Berlin under Soviet control, as it was already within their jurisdiction.
