The correct answer is A. The Domino Theory affected US foreign policy during the Cold War by motivating American leaders to aggressively fight the spread of communism.

Explanation:

The domino theory was based on the assumption that if a country adopted communism, neighboring countries could easily be influenced and adopt this form of revolutionary socialist government. The term "domino" was first used by President Dwight D. Eisenhower on April 7, 1954 during a press conference to describe the rise in the spread of communism in Indochina. This political theory was conceived as a metaphor, and the term "dominoes" refers to the adoption of communism by China in 1949, the increase of communist military campaigns in Korea, and the likelihood that communism will spread to the neighbor countries.

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".
