What icon represents a system list?

The correct choice is based on the iconography used to represent different types of lists or categories within a system. In many applications and systems, icons with varying numbers of figures typically indicate the complexity or the variety of items contained within that list.

In this case, three stick figures convey the idea that the list includes multiple elements or categories, suggesting that it encompasses a more extensive or detailed group of items. This is often used to visually communicate that the selected item or feature has a broader application or more options available.

Icon designs usually aim for clarity and intuitive use. Thus, as the number of figures increases, users can easily recognize that the feature supports a more significant number of items, facilitating a better understanding of the system's capabilities. The icon with three figures strikes a balance between detail and simplicity, making it the most appropriate choice for representing a system list in this context.
