The correct choice highlights the comprehensive nature of access control methods that are critical in maintaining security. ID checks establish the identity of individuals seeking access, ensuring that only authorized personnel can enter a specific area. Security pat-downs further enhance this by allowing personnel to physically check for prohibited items or weapons, providing an additional layer of security. Scanning devices, such as electronic turnstiles or facial recognition systems, help to automate and streamline the process of verifying identities and detecting unauthorized access attempts.

These methods work in conjunction to create a layered approach to security, significantly reducing risks compared to the other options. For instance, unrestricted entry by the public does not provide any security measures and poses significant risks. Visual inspection alone may not be thorough enough, as it relies on individuals being honest about their intentions and may not detect concealed threats effectively. Lastly, relying solely on metal detectors fails to account for other security needs, such as verifying identities and inspecting individuals who may have other types of prohibited items that are not metal. Thus, ID checks, security pat-downs, and scanning devices together represent a robust methodology for effective access control.
