Which pillar runs between the front and rear doors and serves as the mounting post for front door locks and rear door hinges?

• A. B-Pillar
• B. B/Center Pillar
• C. C-Pillar
• D. A/Hinge Pillar

Answer: (B)

The question tests your knowledge of body pillar naming and their functions. The pillar that runs between the front and rear doors and serves as the mounting point for the front door locks and rear door hinges is the center pillar, commonly known as the B-pillar. This vertical member provides structural rigidity to the roof and door openings and houses the hardware that secures the doors—latch/lock components on the front door and hinges on the rear door. The A-pillar sits at the front edge near the windshield, the C-pillar is toward the rear near the back window, and the term D-pillar isn’t a standard reference for this function. So the center pillar is the correct answer.
