Which of the following is NOT likely to be included in a complaint report?

The rationale for the correct answer involves understanding the purpose and content of a complaint report. A complaint report is designed to document incidents, and it typically includes details that are directly related to the incident itself.

Option C stands out because financial history of individuals does not pertain to the specifics of the incident being reported. While understanding someone's financial background may be relevant in certain investigations, it is not a standard component of a complaint report concerning an incident. The report focuses on incident-related information, which includes the precise details surrounding the event, any statements given by those involved (which add context and clarity), and tangible evidence collected at the scene that may support the case or clarify what happened.

The other elements, such as details of the incident, statements from involved parties, and evidence collected, are essential for creating an accurate and comprehensive account of the situation, making them highly relevant to the complaint report.
