Which of the following is associated with Kennedy's nation-building policy among Third World nations?

A) The Limited Test Ban Treaty
B) The Organization of American States
C) The International Monetary Fund
D) The Peace Corps

The Peace Corps was a program established by President Kennedy in 1961 which sent American volunteers to Third World nations to aid in economic and social development. This aligns with Kennedy's nation-building policy aimed at promoting democratic values and economic stability in these nations. The Limited Test Ban Treaty (A) addressed nuclear weapons testing, the Organization of American States (B) is a regional organization focusing on political and economic cooperation among its member states, and the International Monetary Fund (C) provides loans and economic assistance to member countries. While these may have been part of Kennedy's foreign policy, they are not directly associated with his nation-building policy in Third World nations.
