Answer: C. Foreign policy was centralized under the federal government is the correct answer.
Step-by-step explanation:
The articles of confederation had many weaknesses, and to get rid of those constitution was framed. The constitution created a stronger federal government and divided powers between the central and state government. The constitution also had checks and balances to prevent any one individual part of the government from becoming too powerful. It also gave the central government an executive and judicial branch. While under the Articles of Confederation congress could not collect taxes or enforce treaties, it made it difficult for the soldiers to fight the revolutionary war.
