Final answer:
The common goal shared by the Soviet Union, Great Britain, and the United States after World War II was their desire to expand their economic and military presence in various regions, despite their differing ideological frameworks. The correct option is (C).
Step-by-step explanation:
After World War II, the Soviet Union, Great Britain, and the United States had different visions for the reconstruction of Europe and the world. The Soviet Union, having suffered immense losses, sought security by creating a buffer zone of friendly communist states, while the United States wanted to spread the system of capitalism and democracy.
Great Britain, weakened by the war, no longer held its pre-war influence. In essence, none of the options A, B, D accurately reflect the commonality between these nations; however, option C), as they all wanted to expand their economic and military presence in various regions, is the closest to describing their postwar agendas, albeit with differing ideological frameworks.
