Answer:
The correct answer is C, reversing an act of a legislature or executive.
Step-by-step explanation:
Judicial review is wrongly defined in options A and B.
It is correctly defined in C because judicial review means that a court will analyze and invalidade an act of a legislature or executive if it goes against the Constitution. This is how the judicial power stops the other powers from breaking the American laws and violating the separation of powers.
Although such importance, judicial review was established not in the Constitution but in the Supreme Court decision of Marbury v. Madison (1803).
