Which of the following must a license holder disclose to law enforcement?

The appropriate choice is based on the legal obligations of license holders regarding communication with law enforcement. License holders are required to disclose information related to any criminal offense they may be aware of. This obligation exists to ensure public safety and to assist law enforcement in their duties.

When a license holder becomes aware of any criminal activity, it is imperative to report this information to the authorities as it can aid in the prevention of further crimes and the protection of the community. This requirement reflects the broader principle of cooperation between private security entities and law enforcement.

The other options do not align with the specific legal requirements. For instance, disclosing all obtained information without exception is overly broad and may not align with privacy laws or the relevant regulations that govern what information is necessary to report. Similarly, focusing only on financial matters disregards the broader context of criminal activity that needs to be reported. Lastly, while safety protocols are important, they are not legally mandated for disclosure to law enforcement unless they directly relate to a criminal offense.
