Answer:
A
Step-by-step explanation:
Checks and balances refer to the institutional checks of power between the three branches of government. An example of an executive check would be that the Congress has the power to impeach and even remove the President from office. Another one is that the President can veto a law, but the U.S. House can override that veto by a 2/3 vote.
Fun Fact:
Andrew Johnson, Bill Clinton, and Donald Trump are the only three presidents who have been impeached in American history with Trump being the first to be impeached twice. None have ever been removed from office.
