Option B: From an international debtor to an international creditor.
The First World War shifted the USA from owing money to other nations to becoming the primary lender, as it financed war-ravaged European economies.
The source passage (Section 3, Inter-war Economy) references the USA's transformed financial position after WWI. Before the war, the USA borrowed from Europe; after it, the USA lent heavily to European nations, making it an international creditor. Option D is the exact opposite; Options A and C are unrelated transformations.
