Answer:
B). Checks and Balances
Step-by-step explanation:
Not fully sure, but I do know that the President is part of the branches of power, and is meant to create laws and make them a thing. Well, checks and balances makes sure that all the branches are equal and aren't doing the wrong thing. For example here, the President is using Bribery, Treason, and a lot of other bad things. For this, the President is being impeached from their spot to make sure the power of all the branches have the same power.
