What is an outcome of using system variables in a worksheet?

Using system variables in a worksheet serves the purpose of representing selections made in workbook controls. This means that when users make selections through various controls like dropdown menus or checkboxes, system variables capture those choices and allow for dynamic updates of the worksheet based on user input.

These variables are integral in creating interactive and responsive worksheets, where data and visuals can adjust according to user actions. For instance, if a user selects a particular product line from a dropdown, the system variable would reflect that choice, ensuring that any calculations, graphs, or data displays are relevant to the selected product. Thus, this functionality enhances the user experience by making the information more tailored and meaningful.

The other options do not align with the primary function of system variables. While they might touch on aspects of data management or user interaction, they do not specifically describe the core role that system variables play in connecting user actions with worksheet outputs.
