D. It established the authority of the Supreme Court.

Explanation:

Judicial review is the power that the Supreme Court has to review the fairness and constitutionality of the laws and decrees that are promulgated by Congress and by the president, respectively.

The Supreme Court of the United States can review any law or decree, and establish whether it is constitutional or not. In case it finds it is not constitutional, the law or decree is declared null.

In other words, judicial review allows the Supreme Court to check on the power of both Congress and President, and as a result, is part of the system of Checks and Balances of the United States.
