Answer: (B)

World War I is a significant war fought by the United States during the 1900s. The United States entered the conflict in 1917, joining the Allies against the Central Powers. The war was a major turning point in global politics and had lasting impacts on international relations, including the Treaty of Versailles, which formally ended the war in 1919.

This participation showcased the United States’ emerging role as a global power and highlighted the shifts in military tactics and technology during that era. The involvement in World War I was critical for America's military and economic involvement in European affairs and set the stage for its future engagements in World War II and other conflicts throughout the century.
