What allows you to limit the data displayed in a composite worksheet?

Adding a worksheet filter is the correct choice because it directly enables users to refine and limit the data displayed within a composite worksheet. Filters allow you to specify criteria based on which certain rows or data points can be shown or hidden, thereby helping to focus on specific segments or aspects of the data set. This functionality is crucial for data analysis, as it simplifies the view and makes it easier to draw insights from the data.

Utilizing data references, while useful for pulling specific data into a worksheet, does not inherently limit the display of rows or data points. Grouping columns can help in organizing data visually but does not reduce the amount of data shown from the underlying data set. Creating scenario comparisons typically involves analyzing different sets or scenarios of data, rather than filtering down a larger dataset to view a specific subset. Therefore, adding a worksheet filter is the most effective way to limit the data displayed in a composite worksheet.
