Correct answer
Explanation
World War I (1914-1918) marked the end of European supremacy by devastating European economies, destroying empires, and shifting power to the United States. The war bankrupted European nations, led to the decline of colonial powers, and established the US as a creditor nation. It did not strengthen USSR (which emerged from the Russian Revolution during WWI) nor establish immediate US supremacy (that came later).
