Answer: I believe that it is B
Why? The Marshall Plan was an American initiative passed in 1948 for foreign aid to Western Europe. The United States transferred over $12 billion in economic recovery programs to Western European economies after the end of World War ll.
Also you can do process of elimination and say
A makes no sense
C is prohibiting the export of “arms, ammunition, and implements of war” from the United States to foreign nations at war
D again really makes no since
E was put into law by our 5th president in 1823 (World War 11 happened in the 1940s)
So it has to be B
Hope this helps :D
