Which of the following is NOT a duty of a Protective Security Officer?

The answer is C because managing corporate finances is not a duty typically associated with the role of a Protective Security Officer (PSO). The primary responsibilities of a PSO revolve around maintaining safety and security in their assigned areas, which includes conducting patrols to deter and detect suspicious activities, responding to incidents to manage situations effectively and protect people and property, and monitoring security systems to ensure that any threats can be identified and addressed promptly. Each of these duties is directly related to public safety and security, whereas financial management falls outside the scope of a PSO's essential functions and expertise.
