The correct answer is B. As a result of World War I, the United States became the largest creditor nation in the world.
The war consolidated the growth of the United States, whose trade experienced an unprecedented increase to the detriment of the traditional powers of Europe, which lost their foreign markets and saw their economic space fragmented.
The United States lent significant amounts of money to the allies and provided them with ample military equipment and supplies. It became the largest creditor (more than 250 billion dollars) of the European countries, which from then on entered into a close dependence on the North American credits to face the economic reconstruction. The dollar became, along with the sterling pound, the main instrument of change in international transactions and the New York Stock Exchange achieved world leadership.
