Explanation:

The system of checks - and - balances was a key feature established by the Constitutional Convention. Congress has powers to check the executive branch, such as the power of impeachment. The Electoral College was for electing the president, not mainly for limiting executive power. The Articles of Confederation preceded the Constitution. The Three - Fifths Compromise dealt with representation and taxation related to enslaved people, not executive power limitation.

Answer:

C. subjecting the president to checks by Congress.
