Final answer:
The economic development after the American Revolution included implementing a national currency system and establishing the first national bank, paving the way for America's market revolution.
Explanation:
The economic developments that occurred in the years immediately following the American Revolution included the implementation of a national currency system and the establishment of the first national bank. Option B, the establishment of the first national bank, is supported by the historical context provided, which showcases the role of banks and the development of modern banking after the American Revolution.
This development helped set the stage for the market revolution in the early nineteenth century, as the nation transitioned from home production to factory production and traditional controls over production, distribution, and exchange gave way to market transactions based on supply, demand, and price. A major step forward was also taken with the development of interchangeable parts and the integrated mill, which further stimulated this economic transformation.
