Final answer:
The Articles of Confederation established a unicameral Congress with no executive or judicial branches, requiring major legislation to pass with nine state approvals and unanimity for amendments, all of which led to a weak government and the creation of the U.S. Constitution. Therefore, the correct option is B.
Step-by-step explanation:
Under the Articles of Confederation, a unicameral Congress with delegates from each state was the principal governing body in the United States, and there was no separate executive branch or national judiciary. States were considered sovereign and held significant power, leading to a weak national government structure with limited ability to enforce laws or levy taxes. Major legislation required the approval of at least nine states, and any amendments to the Articles needed unanimous consent. After recognizing the weaknesses in the Articles, the U.S. Constitution was created, establishing a stronger federal government through a bicameral Congress and separate executive and judicial branches.
One key issue with the Articles was that it hampered effective governance by requiring a consensus that was challenging to achieve, which ultimately led to its replacement. This shift in governance was a result of discussions and compromises at the Constitutional Convention, leading to a new system of government that balanced the power between the central government and the states.
