What does the term 'banked seating' refer to?

Banked seating refers to a configuration where seats are arranged at an incline, which significantly enhances the audience's viewing experience. This arrangement allows spectators to have a clearer line of sight to the performance stage, minimizing obstructions from other audience members in front of them. The incline helps to elevate the seats further back, ensuring that everyone in the audience has an optimal view, regardless of their position in the theatre.

In contrast, flat seating can lead to sightline issues, where viewers seated further back may struggle to see over those in front. Other configurations, such as individual boxes or removable seats, serve different purposes that do not specifically enhance viewing angles in the same way that banking does. Therefore, banked seating is specifically designed for improved visibility, making it the correct answer.
