Which of the following penalties can be imposed for violating section 4749.13?

For violations of section 4749.13, the penalties can range in nature, allowing for both a fine and imprisonment to be imposed. This section typically addresses serious infractions related to security services, which can warrant severe repercussions to ensure compliance and maintain the integrity of the profession. A combination of penalties reflects the gravity of the offence and serves as a deterrent for future violations. While a fine or imprisonment could be standalone consequences for different infractions, the inclusion of both penalties here indicates that the law is designed to tackle more severe violations with a comprehensive approach.

In the context of the provided choices, the other options fail to capture the full scope of potential penalties that can be enforced, which specifically include both components of a fine and imprisonment for certain serious breaches outlined in this section. Community service, while often a penalty for minor offences, does not align with the serious nature of the violations that section 4749.13 addresses.
