Answer:
C - required unanimous state consent to amend it
Step-by-step explanation:
The Articles of Confederation had many weaknesses.
1) Unanimous state consent to amend.
If there was even one state that disagreed, the articles cannot be added. As states ran almost autonomously from each other, each one had their own foreign relations and dealings, leading to them not being able to agree.
2) No power for central government.
The Articles of Confederation created a centralized government, known as the federal government, but did not give it any powers. It did not have the power to tax, create an army, or even deal with foreign powers. In essence, it was just a puppet government that barely held the confederation together.
3) States were barely held together, and did not have to come to the aid of each other. Each state pretty much looked out for themselves, which led to large weaknesses when foreign powers invaded. This was later amended inside the Constitution.
