The correct answer is A. The Truman Doctrine was designed to contain Communism where it was and prevent it from spreading to other nations.

Explanation:

The Truman Doctrine is a foreign policy program announced by US President G. Truman after World War II in a speech to Congress on March 12, 1947.

It formulated the policy of “containment” in relation to Soviet Communism in the whole world. It was aimed at revising the system of international relations that had formed under Roosevelt. Truman Doctrine was aimed at the struggle of the United States and its supporters for the political and economic unipolarity of the world.

The “Truman Doctrine” was aimed at limiting the growth of the forces of socialism that intensified after World War II, exerting continuous pressure on the USSR and other totalitarian countries, and supporting democratic forces and regimes.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
