D. It created a weak federal government with no powers to impose taxes or regulate trade.
Explanation:
The Articles of Confederation constituted the first document that established what the US government would be like, shortly after independence. The articles were created in November 1777, after much debate and conversation between the founders and several men. They were ratified on March 1, 1781 and although all their formulation was done with the intention of creating a strong and sovereign government that would lead the country to great prosperity, it created a weak federal government, with no powers to impose taxes or regulate the trade. This created several problems in the management of the country, leaving it weak and disunited. However, the articles of the confederation were replaced by the American federal constitution (which solved all these problems) on June 21, 1788.
