The correct answer is B. Germany was divided into four occupation zones, each controlled by an Ally.

Explanation:

After the Potsdam Conference, Germany and Berlin were divided into four sectors of occupation: Soviet, American, French and English. The bad relations between the communists and the allies grew until they reached the point where two currencies emerged, two political ideals and, finally, two Germanies.  

In 1949, the three western sectors (American, French and British) were renamed the Federal Republic of Germany (FRG) and the Eastern (Soviet) sector became the German Democratic Republic (GDR).  Berlin was divided and 81 crossing points were created between the two zones of the city.
