Final answer:
The Congress, as per the Articles of Confederation, held the primary decision-making power as there was neither an executive office nor a judiciary at that time.
Step-by-step explanation:
Under the Articles of Confederation, the most important governing decisions were made by The Congress, option B. The Articles of Confederation served as the written document that established the functions of the national government after it declared independence from Great Britain, and in this first form of federal governance, there was no executive office or judiciary. As such, Congress was the principal decision-making body. Each state delegated representatives and had just one vote, regardless of its size, thereby maintaining the autonomy and sovereignty of the states.
