Final answer:
Technician A is correct. The chassis includes everything but the body, while the body is separate and covers the internal components of the automobile. The correct answer is (A) Technician A.
Step-by-step explanation:
The chassis of an automobile typically includes everything except the body. The chassis is the structural framework of a vehicle, encompassing components such as the frame, suspension system, steering mechanism, and wheels. It provides support for various vehicle systems and serves as the foundation for attaching the body, engine, and other essential components.
On the other hand, Technician B is incorrect. The chassis is not just another name for the vehicle's body; rather, it is a distinct and separate component that forms the structural base of the automobile. The body is mounted onto the chassis and includes features like the car's exterior panels, interior components, and other non-structural elements. In summary, Technician A accurately describes the chassis as excluding the body, while Technician B's statement is inaccurate. Therefore, the correct answer is (A) Technician A.
