The correct answer is D. They explained how the constitution provided checks and balances on the president’s powers.
During the Constitutional Convention, members of this committee who were Anti-federalists feared a extremely strong federal (central) government. These fears were rooted in America's experience as colonists under the control of Great Britiain and King George III.
To ease the fears of these Anti-federalists, the federalists discussed how the new constitution set up a balance of power between the different branches of the federal government. The judicial and legislative branch were both able to check the executive branches power. The judicial branch has the power to rule executive orders made by the president as unconstitutional while the legislative branch could override a presidential veto if needed.
