Retention1 is configured to “retain items for 6 months and then permanently delete” and to start the period “when items were created.”

File1 is created 1 Jan 2020, so its 6-month retention period ends 1 Jul 2020.

Because the file is subject to a retention label, the user’s deletion on 1 Feb only moves it to the Preservation Hold library; it cannot be removed before the retention period expires.

When the period ends, the SharePoint/OneDrive cleanup job permanently deletes the file (within 1–7 days), so the first possible date it can be unrecoverable is 1 Jul 2020.

Therefore, option B is correct.

A. February 1 – Retention label blocks permanent deletion until the 6-month period expires.

C. July 10 – Would apply only if the label was based on “last modified”; the exhibit shows “when created.”

D. August 1 – Six months after deletion; retention period is calculated from creation, not deletion.
