Which statement about the filter tool is correct?

The correct statement about the filter tool is that the drop-down list of operators changes based on the data type. This feature allows users to select appropriate comparison operations tailored to the specific type of data being evaluated, such as string, numeric, or date types. For instance, when filtering numeric data, options like greater than or less than become available, while for text data, string-specific comparisons like 'contains' or 'starts with' are presented. This dynamic adjustment ensures that users can create meaningful conditions that accurately reflect the nature of the data they are working with.

In contrast, the other options lack accuracy related to the filter tool's functionality. For example, the output of records from a filter tool cannot exceed the number of records input; the tool is designed to narrow down the dataset, so the output can only be equal to or fewer than the records provided. Additionally, expressions created within the filter tool can be saved and reused in other contexts or tools within Alteryx. Lastly, the filter tool is fully capable of handling text fields as part of its filtering capabilities, allowing users to apply conditions based on text data.
