Question

Quizplus · Accepted Answer

Technician A is correct because unibody construction integrates the body and frame into a single unit, reducing weight compared to body-on-frame vehicles. Technician B is correct because in body-on-frame construction, the vehicle's components, including the engine, body, and suspension, are mounted on a separate frame.
