What is an appropriate use for the 'For Each Row' activity in UiPath?

The 'For Each Row' activity in UiPath is specifically designed for iterating through each row in a DataTable. This activity enables automation processes to efficiently handle data stored in tabular formats, such as those found in Excel spreadsheets or databases. With this activity, users can perform operations on each row's data, allowing for actions like data extraction, modification, or validation in a structured manner.

By applying the 'For Each Row' activity, a developer can easily access each column value within the row context, making it exceptionally useful for tasks that require operations on a dataset. This functionality supports various automation scenarios, from generating reports to conducting data checks, which are common tasks in business processes.

In contrast, extracting data from a single text file does not involve row iteration and would require different activities tailored to file handling. Similarly, sorting data in ascending order does not align with the purpose of the 'For Each Row' activity, as sorting is a data manipulation operation typically handled separately. Lastly, pausing automation execution is unrelated and involves different mechanisms to control the flow of the automation process. These distinctions highlight why the focus on iterating through DataTable rows makes option B the appropriate choice for the 'For Each Row' activity.
