Answer:
B. Each region fell under the influence of a foreign superpower.
Step-by-step explanation:
After the war, Europe was divided into two blocks. One dominated by the Soviet Union and another by the Allies, particularly, the US.
Both foreign powers devised similar measures and policies to control the expansion of the other. The US promoted the Marshall plan and the USSR pushed for the Comecon, using commercial ties and economic aid to control their respective area of influence.
