Which of the following is a system-generated stamp?

A system-generated stamp is one that is automatically created by a digital system without the need for manual input. The "CTO Submit" is an example of such a stamp because it is generated by the system during the submission process, indicating that the submission has been entered properly and processed according to the system's workflow. This stamp helps maintain the integrity and traceability of the submission while reducing the chance of human error.

In contrast, the "Pre-Audit Review" is likely a step in a procedural process that involves human assessment, rather than a stamp generated by the system itself. The "Approval Stamp" could imply a manual action where a person explicitly grants approval, thus it isn't system-generated. The "Manual Entry Stamp" suggests that the stamp is applied through manual input, which again does not qualify as system-generated. Therefore, "CTO Submit" stands out as the correct answer since it is an automatic, system-produced record of an action taken within the digital workflow.
