The B-pillar is located between which parts of the vehicle?

• A. Between the roof and floor
• B. Between the front door and rear door
• C. Between the front windshield and front door
• D. Between the trunk and rear bumper

Answer: (B)

In vehicle body terminology, pillars are vertical supports labeled A, B, C, etc. The B-pillar is the structural post that sits between the front door and the rear door on the same side of the car. It helps carry roof load down to the floor and adds rigidity, which is important for side-impact protection and door alignment. That makes the B-pillar the post located between the front and rear doors.

For context, the A-pillar sits between the windshield and the front door, and the C-pillar is near the rear side window toward the back of the car. The other options don’t describe the location of the B-pillar: it isn’t between the roof and floor, nor between the front windshield and front door, and there isn’t a pillar specifically described as between the trunk and rear bumper.
