What action should be selected to revoke the arrival at an assignment?

Selecting the action to revoke the arrival at an assignment is accurately identified as "Revoke Arrival" because this terminology is commonly used in systems managing assignments or workflows to indicate the formal process of reversing an arrival status. This action typically suggests that the assignment or task that had previously been marked as "arrived" is now being changed back to a status as if it had never arrived. This is crucial in environments where tracking the status of tasks is essential for proper management and record-keeping.

In contrast, other options like "Cancel Arrival" might imply stopping the process altogether, rather than simply negating the arrival status. "Remove Arrival" could be misinterpreted as just deleting the record rather than formally changing the status, and "Withdraw Arrival" might suggest pulling back from a commitment without formally updating the assignment's current state. Therefore, "Revoke Arrival" is the clearest and most appropriate action to take when specifically wanting to reverse an arrival status on an assignment.
