Answer:
C. Economic prosperity followed World War I
Explanation:
The outbreak of World War I marked the end of a stage in the international economy characterized by a sharp increase in trade in goods and services, and by the flow of capital and migratory flows from Europe to the other side of the Atlantic. Although few perceived it at that time, the Great War cracked the system by putting an end to British hegemony and strengthening protectionist tendencies that had been accentuated in Europe, the United States and Japan since the end of the 19th century.
Although the First World War damaged the economy of many of the European countries, as a result of the reconstruction plans and the rise of the industry, the economies returned to rise and became phosphorous until the great crisis.
