This pillar extends up sides of windshield from the main body to the roof. It also provides mounting posts for the front door hinges, windshield, cowl, and front corners of roof.

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

Answer: (A)

The pillar described is the one at the front edge of the windshield, running up from the body to the roof and providing the mounting posts for the front door hinges, the windshield, cowl, and the front corners of the roof. This is the A-pillar (often called the hinge pillar) because it sits along the sides of the windshield and supports those critical attachments. The other pillars have different locations: the B-pillar is the center post between the front and rear doors, the C-pillar is around the rear window area, and the D-pillar is the rear-most pillar on some body styles. So the described features align with the A-pillar.
