<em>A. Congress was denied power to regulate trade.</em>
Explanation:
The Articles of Confederation had many weaknesses, it did not give proper power to the national government, so they could not regulate trade, enforce laws, or tax citizens. Colonists were scared that if enough power got into the hands of the government, the same thing would happen with what happened with Great Britain. Although the national government had no judicial branch, would also be correct in this case, as the national government did not have enough power or resources to do so, the question states "mercantile laws", which have to do with trade. Congress did not have any power to regulate trade under the Articles of Confederation, as they hated how the British used to enforce laws on them about what they can and cannot trade, and who they can and cannot trade with.

The most important reason for the collapse of Rome was the failure to actually integrate what they conquered. When Roman soldiers conquered new lands, it was rare that they ever attempted to force their culture, ideals, or laws upon the natives and barbarians. Thus, when the Empire began suffering internal struggles, the natives they had conquered decided to take action, which lead to the swift collapse by barbarian invasion from all sides. It's hard to pick a LEAST important reason, seeing that there were many of them, but I suppose a contender would most likely be the common refusal of the Empire to even acknowledge that barbarians were rising. On the outer edges of their territory, in places like Gaul and Morocco, the Roman government was reluctant to even recognize the threat of the barbarians, thinking that even accepting that these barbarians were causing trouble would weaken their prestige in the public eye.
