The correct answer is C. Ideas regarding underdevelopment were popularized by President Truman in his 1949 inaugural address. He stated that nations in the Southern Hemisphere were "underdeveloped areas" because of their low gross national product.

Explanation:

Truman was born into a Missouri family of farmers and had no opportunity to study at university. He worked as a farmer for several years and then participated in the First World War as a reserve officer in the artillery. He served for a time on the French front. After being a partner in a clothing business in 1919-1922, Truman began his political career as a local politician, with the support of the influential Pendergast family. In 1934 he was elected to the United States Senate but was met by suspicions from the Roosevelt administration because of his association with Pendergast. He was nominated as Vice Presidential candidate in 1944 and took up the post on January 20, 1945, following the Democrats' victory in the 1944 presidential election, after Roosevelt's death. He was reelected by a surprising victory in the 1948 presidential election.  

Truman did not run for re-election in the 1952 presidential election. He was succeeded as president by Republican Dwight D. Eisenhower, who defeated Democratic candidate Adlai Stevenson. Truman had low popularity from time to time during his tenure and was heavily employed by political opponents, but today his views on his presidency are more positive and he is considered one of the country's top ten presidents.
