Answer:
The correct answer is B.
Step-by-step explanation:
Both the Marshall Plan and the creation of the United Nations were two cornerstones in the process of world reconstruction after World War II. Thus, both were in charge of generating the conditions for a better political, economic and social development of the nations, with the aim of avoiding the development of new tensions worldwide.
Now, there was a clear difference between the two projects: while the United Nations encompassed all the nations of the world, even giving the USSR a seat on the Security Council, the Marshall Plan focused on Western Europe, seeking to generate conditions of economic welfare in this region, to avoid the emergence of communism there.
