The correct answer is D) it can declare presidential actions unconstitutional.
<em>The Judicial branch checks the powers of the executive branch in that it can declare presidential actions unconstitutional.
</em>
In order to eliminate the possibility that one power had more faculties and could control the other two, the United States Constitution created a doctrine of System of Separation of Powers and a Check and Balance System. This way, the Constitution defines clearly the power of the Executive branch (the Presidency), the Legislative branch (the Congress), and the Judicial branch (the Supreme Court). In the case of the question, the Judicial branch checks the powers of the executive branch in that it can declare presidential actions unconstitutional.
The question will be more answerable if the entries are there.
