Final answer:
Option D. The Articles of Confederation created a weak federal government, while the U.S. Constitution established a stronger federal government with expanded powers, such as enforcing laws, collecting taxes, and raising an army.
Step-by-step explanation:
The difference between the Articles of Confederation and the U.S. Constitution lies primarily in the distribution of power between the federal government and the states. Under the Articles, a weak federal government relative to the states was intentionally established to prevent abuses of power, reflecting the recent experiences with British rule. This structure made the federal government incapable of enforcing laws, taxing, or raising an army effectively. In contrast, the Constitution created a stronger federal government, making it the supreme law of the land, capable of addressing national issues more effectively than the Articles permitted. Changes included the establishment of a bicameral Congress with expanded powers, an executive branch to enforce laws, and a federal judiciary to resolve disputes.
