What role does the auditor play in the audit submission checklist?

In the context of an audit submission checklist, the auditor's primary responsibility includes ensuring that the checklist is thorough and complete, which aligns with the correct choice. Completing the checklist is a critical task because it helps to verify that all necessary documents and information have been gathered and reviewed before the final submission of the audit. This thoroughness is essential for maintaining the integrity and reliability of the audit process.

While compliance assessment, reviewing findings with management, and delivering training are all vital components of an auditor's overall responsibilities, they do not directly pertain to the specific function of completing the audit submission checklist. Completing the checklist involves methodically ensuring that every required element has been accounted for, which ultimately contributes to a more effective audit process and enhances the quality of the final audit report.
