A is the correct answer.
Up until the early 1800s, and really until today, States do not get along when it comes to money. The Articles of Confederation purposefully had a weak central government and no national currency as each State had its own war debt and some were quicker to pay it off than others. Currency needs to be back by something, so, the more prudent states opposed the freeloading of the less prudent and more debt ridden states.
