D: Judicial review
Judicial review is the ability of a court to examine and decide if a statute, treaty or administrative regulation contradicts or violates the provisions of existing law, a State Constitution, or ultimately the United States Constitution. While the U.S. Constitution does not explicitly define a power of judicial review, the authority for judicial review in the United States has been inferred from the structure, provisions, and history of the Constitution.
