Welche Länder wurden nach dem Zweiten Weltkrieg in Deutschland als "Alliierte Besatzungsmächte" bezeichnet?

Why this is the correct answer

After Germany's defeat in May 1945, the four main Allied powers — the United States, the Soviet Union, the United Kingdom, and France — each took control of an occupation zone carved out of German territory. Berlin, deep inside the Soviet zone, was similarly divided into four sectors. This arrangement eventually hardened into the division between West Germany and East Germany that persisted until reunification in 1990.
