Which of the following refers to an expansion of US influence through economic means?

The term that refers to the expansion of US influence through economic means is Dollar Diplomacy. This strategy was particularly associated with President William Howard Taft's administration in the early 20th century. It emphasized the use of financial investments and loans to extend American influence, particularly in Latin America and East Asia. By encouraging American businesses to invest in foreign countries, the U.S. aimed to foster stable economies that would be conducive to political stability and American interests.

In contrast, Cultural Hegemony refers to the dominance of one culture over others, typically through social or cultural means rather than economic strategies. Manifest Destiny is the 19th-century doctrine that the expansion of the United States across the American continents was both justified and inevitable, focusing primarily on territorial and political expansion. Territorial Expansion specifically deals with the physical acquisition of land rather than the economic influence and manipulation that Dollar Diplomacy exemplifies.
