Which option in the Contents Pane lists layers by object selection count?

The option that lists layers by object selection count is the one that allows users to organize and manage their layers based on how many features within those layers are currently selected. This is particularly useful in GIS applications when you are working with multiple layers and need to quickly identify which layers contain selected features, facilitating a more streamlined data analysis and visualization process.

When using the choice that organizes layers by selection, it aids in assessing the focus of your current analysis. If you have selected features in a layer, it will be listed prominently, allowing you to quickly see which layers are relevant to your current task. This is especially important in complex projects where understanding the relationship and interaction between different layers is key.

In contrast, other organizing options focus on different aspects of the data. Listing by attribute would sort layers based on their associated attributes, listing by name arranges them alphabetically, and listing by visibility simply shows layers based on whether they are turned on or off in the map. Each of these strategies serves a different function, but none specifically prioritize the count of selected features except for the option that lists by selection.
