What documents must vehicle's registration papers include?

The correct answer highlights the essential documents that should be included in a vehicle's registration papers. Specifically, the receipt for license plates demonstrates proof of the acquisition of license plates necessary for operating the vehicle on public roads. Vehicle weight information is also a critical component, as it can determine registration fees and compliance with various regulations concerning weight limits for vehicles on different types of roads.

Other options, while related to vehicle documentation and regulation, do not represent the standard requirements for vehicle registration. Insurance details and owner's identification are typically required for registering a vehicle but aren't specifically part of the registration papers themselves. Operational history and service records are useful for maintenance and resale purposes, but they are not part of registration documentation. Similarly, vehicle inspection records and emissions tests, while important for compliance and safety, are not typically found within the registration papers but rather may be needed for compliance checks or renewals.
