Answer:
They did not want to have to help pay off other states' debts.
Explanation:
The Southern states oppose Hamilton's plan because "they did not want to have to help pay off other states' debts."
This is because before Alexander Hamilton makes the proposition, the majority of the southern states had actually paid off their wartime debts using their own money.
Thereby many of them believed other states of the United States should also pay their own debt, without assistance from other states.
Hence, in this case, the correct answer is "They did not want to have to help pay off other states' debts."
