Answer:
A. The United States limited its involvement in international affairs.
Step-by-step explanation:
It is not B, as: The United States did in fact create the League of Nations, but dropped out soon after as it was extremely unpopular in the eyes of the US public, who still wanted to continue the policy of isolationism.
It is not C, as: The United States may have created loan projects, but they did not pay for the rebuilding of Great Britain and France. The only time they did so was after World War II, with the Marshall Plan, which gave money in grants or loans to European states which were anti-communist or broke away from the Iron Curtain.
It is not D, as: The United States did not continue the policy of Imperialism. They did not take much (if any) territories from their European Rivals. Most of the colonies were transferred either to France, Great Britain, or occupied by Japan, or else granted independence.
