Final answer:
A passenger in a vehicle has the same right as a driver to challenge the constitutionality of a traffic stop.
Step-by-step explanation:
The correct answer is A) True.
A passenger in a vehicle does have the same right as a driver to challenge the constitutionality of a traffic stop. This is because the Fourth Amendment of the United States Constitution protects against unreasonable searches and seizures, and applies to both drivers and passengers in a vehicle. If the passenger believes that the traffic stop was conducted in violation of their constitutional rights, they can challenge it in court.
