A
Explanation:
In the United States, 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.
I believe it is precedents because they use the rulings of previous cases to help their decision:) but judicial review and judicial activism have been used by some supreme courts :)
