Answer:
b. The supreme court
Explanation:
The Supreme Court is responsible for interpreting and evaluating the Constitution, as well as for determining the constitutionality of the laws enacted by the Congress, and the actions performed by the Executive branch.
Likewise, when parties are not satisfied with a decision of a lower court, especially when the ruling apparently conflicts with the Constitution, the person may petition the U.S. Supreme Court to review their case. If the Supreme Court decides to hear the case, it acts as the final authority to decide the constitutionality of the previous ruling.
