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

The hatchback is the appropriate choice as it refers to a vehicle design where the rear cargo area is accessible through a large door that swings upward, combining the deck lid and the stationary back glass into one assembly. This design allows easy access to the rear storage area of the vehicle, providing both functionality and enhanced aerodynamics.

In a hatchback, the rear glass is typically integrated with the rear door, allowing for an expansive opening that can accommodate larger items and providing practical use in daily driving scenarios. This setup contrasts with other vehicle components:

• The sail panel is a small section of bodywork positioned between the rear window and the rear side windows, mainly serving decorative and structural purposes rather than providing access to the rear compartment.

• The tail panel is located at the rear of the vehicle and often houses features such as lights, but it does not serve the purpose of combining a lid and glass into a single assembly.

• The fender is the panel that frames the wheel wells and does not relate to the rear access or the integration of the glass and lid.

Thus, understanding the design and functionality of the hatchback clarifies why it is the correct choice.
