What component combines the deck lid and stationary back glass into a single assembly that lifts up like a deck lid?

The correct response is a hatchback, as it is a specific design of a vehicle's rear section that combines both the deck lid and stationary back glass into one cohesive unit. This configuration allows the entire rear assembly to lift upwards, providing access to the trunk area. The hatchback design is popular for its versatility, as it not only enhances the vehicle's aesthetic appeal but also increases practicality in terms of cargo space and ease of loading and unloading.

In contrast, a fender is a component that frames the wheel wells of a vehicle and does not lift or provide access to the cargo area. The tail panel is a structural piece located at the rear of the vehicle but does not serve the same functional capacity as a hatchback. Lastly, the sail panel refers to the side section of the rear windows or structure of a car, which also does not play a role in lifting or accessing the vehicle's cargo space. Understanding these terms helps clarify why the hatchback is the appropriate choice in this context.
