The correct answer is "A".
The Second Continental Congress passed the Articles of Confederation in November 1777. The original draft was elaborated after approximately a year of debate. However, it took nearly 3 and a half years to ratify the articles, as the main issue of debate, which was the representation of each state, represented an obstacle. After an initial round of voting which was not unanimous, an agreement was reached during a second round of voting on December 16, 1777.
