Answer: D. banks in northern states
Explanation: As Secretary of the Treasury under Thomas Jefferson, Alexander Hamilton called for greater government control over the national debt. He called for the Federal government to assume the debts of all states. This would not only increase the power of the national government, but it would aid banks in northern states, who held the notes on many of those loans. They would be guaranteed of not only getting their money back, but of making a hefty profit. Most of Hamilton's plan was eventually passed.
