What can you modify using the "Chart Tools" in Excel?

Using "Chart Tools" in Excel allows you to modify charts specifically to enhance their presentation and data visualization. This toolset provides various features that enable users to change chart types, styles, colors, and layouts, as well as add elements such as titles, data labels, legends, and gridlines. These modifications are essential for creating clear and effective visual representations of data, making it easier for the audience to interpret and analyze the information conveyed by the charts.

The other options address different aspects of Excel functionality. Options about modifying the content of cells, changing the size and position of the worksheet, or altering the overall layout of the workbook pertain to general worksheet capabilities rather than the specific enhancements made possible by the Chart Tools feature. Therefore, the focus of Chart Tools is distinct and uniquely concentrated on improving chart-based visualizations rather than broader workbook or worksheet alterations.
