Answer:
A) checks and balances
Explanation:
The system of Checks and Balances is the system whereby all three branches of the government (the Legislative, Executive, and Judicial) respond to the action of the other and oversee, limit and check the other in order to prevent one branch from becoming too powerful and abuse of its power.
For example, under this system, the Judicial branch has the authority to declare the unconstitutionality of laws passed by the Legislative and acts of the Executive, and at the same time, the President is responsible for appointing the Justices of the Supreme Court, and the Legislative is responsible for confirming or rejecting those nominees.
