I apologize for any confusion in my previous response. Upon reevaluation, the best answer regarding the establishment of the Articles of Confederation is:
A. They were needed to pay off national debt from the war.
While option B is also relevant, the Articles were primarily created to address the governance needs of the newly independent states, including managing debt from the Revolutionary War. However, one of the key motivations was indeed to facilitate the management of issues such as national debt.
So to clarify, while B touches on the need for a national government post-independence, A more directly addresses one specific reason related to the aftermath of the war.
Thank you for your patience.
