Final answer:
The statement is True as the 'C pillar' of a vehicle connects the rear window to the rear side windows or rear door frame.
Step-by-step explanation:
The vertical supports connecting the roof of a vehicle to the body are often referred to as the pillar. In the context of cars, the 'A pillar' is the one that connects the front side of the roof to the car body, commonly framing the windshield. The 'B pillar' is the one that connects the roof to the car body at the rear of the front doors, and the 'C pillar' is the one that connects the rear sides of the roof to the car body, usually framing the rear side windows or the rear door frame. Hence, the statement that a 'C pillar' connects the rear window to the rear side windows or rear door frame is True. Some vehicles, such as station wagons or SUVs, may also have a 'D pillar.'
