Which feature in Excel allows for dynamic data tracking?

The feature in Excel that allows for dynamic data tracking is conditional formatting. Conditional formatting enables users to apply specific formatting to cells based on their values or content. This means that as the underlying data changes, the formatting will automatically adjust to reflect the current state of the data. For example, if there is a rule set that highlights cells in red when values fall below a certain threshold, any changes to those values will cause the formatting to update accordingly. This dynamic visual feedback makes it easier for users to track changes and identify trends or outliers in the data.

In contrast, other options do not provide the same level of dynamic response to data changes. Data protection is focused on securing the integrity of data rather than tracking changes, range names are primarily used to simplify referencing cell ranges in formulas, and data filtering allows users to view specific subsets of data but does not change the appearance or provide visual tracking as data evolves.
