Which of the following agencies carries out scrutiny of vehicles for roadworthiness in Nigeria?

The agency that carries out the scrutiny of vehicles for roadworthiness in Nigeria is the Vehicle Inspection Office (VIO). The VIO is responsible for ensuring that vehicles operating on Nigerian roads are safe and roadworthy. They carry out inspections of vehicles to check for things like functioning brakes, lights, tires, and other safety features. They also verify that the vehicle's papers are up-to-date and valid. The Nigeria Security and Civil Defence Corps, the Nigeria Police, and the Nigeria Customs Service have other roles in enforcing the law and maintaining security but do not carry out the scrutiny of vehicles for roadworthiness. Therefore, the correct option is "Vehicle Inspection Office."
