You have a Microsoft 365 subscription that uses Microsoft Purview and Microsoft Teams.

According to Microsoft Purview and Kusto Query Language (KQL) documentation, when you need to filter audit or activity logs based on a specific date range, the correct approach is to use the between (datetime()..datetime()) operator. This operator allows defining a start and end datetime for filtering events. The AuditLogs table is the appropriate data source for searching Microsoft 365 audit events, including file activities in SharePoint and Teams sites.

In this scenario, the goal is to identify all files related to “Project1” stored on the Team1 site between February 1, 2023, and February 10, 2023. The where clause is used to filter the results first by Timestamp (activity date/time) and then by FileName to find the relevant project files.

The correct syntax aligns exactly with the Microsoft KQL documentation pattern:

| where Timestamp between (datetime(StartDate)..datetime(EndDate))

This ensures that only audit records falling within that time window are retrieved.

Other options are incorrect because they either lack valid KQL structure or use unsupported syntax for date ranges. Thus, Option D is the verified answer.
