The correct answer is A) They had differing ideas about a powerful national government.
After the Revolutionary War, states were consistently worried about the power of the national (central) government. Considering that one of the biggest reasons for breaking away from England was a tyrannical central government, helps to understand why there were differing ideas about the structure of the American govenrment when the US became independent.
This is why the United States, under the Articles of Confederation, had a small and weak central government. Some states liked this while other states felt that this central govenrment was too weak to function effectively.
