Answer:
The correct answer is A. Delegates were working to replace the Articles of Confederation because they created a central government that was too weak.
Step-by-step explanation:
The Articles of Confederation formed a weak confederation that united the Thirteen Colonies, with the capacity to govern themselves almost only in times of war and emergencies. Congress could make decisions, but did not have the power to apply them. The biggest setback was the requirement of unanimous approval of the Thirteen states to modify the articles. At the same time, the most important power that Congress lacked was the power to collect taxes: it could only request money from the States. These, for their part, did not always comply with the demands and Congress did not have the necessary funds for its operation.
After the end of the War of Independence and the beginning of new priorities, its limitations became evident. This document was replaced by the Constitution of the United States after its ratification on June 21, 1788.
