The main idea here is identifying which institution belongs to the judicial branch—the branch that interprets laws and settles disputes. The Supreme Court is the highest court in the United States and sits within the judicial branch; it reviews laws and actions to determine if they follow the Constitution and can overturn or strike down those that don’t. In contrast, the Senate is part of the legislative branch that makes laws, the President leads the executive branch that enforces laws, and a Mayor is local government, not a federal branch. So the Supreme Court is the correct choice because it represents the judicial branch.
