What type of door is constructed with three or four sections that rotate in a circular frame?

The correct answer is revolving doors. These doors are specifically designed with three or four sections that rotate around a central axis within a circular frame. This design allows for efficient foot traffic flow while minimizing the exchange of air between the interior and exterior of a building, which can help maintain climate control and energy efficiency.

Revolving doors also provide a barrier against wind and weather, enhancing the comfort of individuals entering or exiting a building. Their unique mechanism differentiates them from other types of doors, such as swinging or sliding doors, which do not have this rotating configuration. Swinging doors move on hinges and typically open in one direction, while sliding doors operate along tracks. Glass doors can refer to any door made primarily of glass but do not inherently describe a specific operational mechanism like revolving doors do.
