Which component falls under Major Component Parts?

The correct selection pertains to major component parts that are crucial to the operation and safety of a vehicle. Components such as the engine and transmission systems play vital roles in ensuring that the vehicle operates efficiently and safely. The engine is responsible for generating power, while the transmission transmits that power to the wheels, making them essential for the vehicle's functionality.

In contrast, while brakes and lighting systems are also critical for safety, they are typically categorized under different systems related specifically to safety and operational readiness. Rims and tires, although important for vehicle mobility and drive quality, might be considered more in the realm of accessories. Paint and exterior designs are aesthetic elements and do not directly influence the mechanical operation or safety of the vehicle, placing them outside the scope of major component parts. Thus, the engine and transmission systems are properly classified as major components due to their fundamental importance in vehicle operation.
