What type of report identifies the case and presents all available facts?

The correct response is the preliminary report, as it serves the purpose of identifying the case and presenting all available facts at the initial stage of an investigation. This report is crucial for laying the groundwork and providing a comprehensive overview of the situation as it stands, including key details that can guide further investigative efforts.

A preliminary report typically includes initial findings, observations, and any relevant evidence collected up to that point. Its primary aim is to summarize what has been discovered, rather than draw any conclusions, making it essential for keeping all stakeholders informed about the progress and status of the investigation from the outset.

The final report would generally summarize the entire investigation and its conclusions, whereas a progress report would focus on updates during the investigation without presenting all facts at the initial stage. An observation report typically records specific insights or data about the subject being investigated but does not encompass the full range of facts related to a case.
