Which plan was used as a strategy to block Communist expansion by supplying funds to Western Europe?

The Marshall Plan was a significant strategy implemented after World War II to aid in the economic recovery of Western European nations. Launched in 1948, the plan provided substantial financial support and resources to help rebuild war-torn countries, promote economic stability, and prevent the spread of Communism.

By supplying funds and facilitating the rebuilding of European economies, the Marshall Plan aimed to create prosperous and democratic societies that could resist communist influence, especially in the context of the Cold War. The infusion of American financial aid helped countries to rebuild their infrastructures, stabilize their economies, and revive trade, thereby reducing the appeal of communist ideologies among the populations of these nations.

The other options, while related to various aspects of post-war policies, do not specifically involve the economic support aimed at bracing Western Europe against Communism. The containment strategy refers more broadly to the U.S. foreign policy aimed at preventing the spread of communism, while the Ford Foundation and the economic recovery plan are not linked directly to this specific context of facilitating economic recovery in Europe following World War II.
