The correct answer is A) The Judicial Power shall extend to all cases, in law and equity, arising under this Constitution, the laws of the United States, and Treaties made, or which shall be made, under their authority;
The idea of judicial review allows the Supreme Court to interpret what the constitution means. This important judicial power ensures that the Supreme Court has the ability to check the power of the legislative and executive branches. This is due to the fact that judicial branch can get rid of any law that violates the civil liberties of citizens if it is made by one of the other two branches of the federal government.
