Hamilton's proposal that the federal government repay all foreign loans, repay government certificates at face value, and assume the debts of the states was called the
a. repayment plan.
b. commerce plan.
c. assumption plan.
d. debt plan.

D. Debt plan.

Explanation:

Following the Revolutionary War, the United States had a debt of $54 million dolars, plus the $25 million debt taken by the states. Hamilton's debt plan was to nationalize and settle that money with Treasury bonds.

The debt plan combined and transferred the entire country's war debt to be paid off by the national authority. Hamilton´s ultimate goal for this plan was to strengthen the national commercial and political power.  

the navigation act prevented the colonies from exporting to countries other than britain and it prevented the importation of goods by other countries as well. so i believe the correct answer is d. other nations could not deliver goods to the colonies.
