Final answer:
Option D) The Senate approves the President's nominee for Supreme Court justice is not an example of the checks and balances system.
Step-by-step explanation:
The correct answer is option D) The Senate approves the President's nominee for Supreme Court justice. This is not an example of the checks and balances system because it is a part of the process of appointments and confirmations, rather than a direct check on another branch of government. The power of the Senate to approve or reject the President's nominee for Supreme Court justice is outlined in the Constitution as a separate responsibility of the legislative branch.
