C) trade monopoly in asia
answer= checks and balances
Explanation:
Federalist No. 51 addresses means by which appropriate checks and balances can be created in government and also advocates a separation of powers within the national government. This idea of checks and balances became a crucial document in the establishment of the modern U.S. system of checks and balances.
The Articles required unanimous consent to any amendment, so all 13 states would need to agree on a change. Given the rivalries between the states, that rule made the Articles impossible to adapt after the war ended with Britain in 1783.
