The correct answer focuses on how iOS and iPadOS enforce app security through the prevention of unsigned apps from being installed. This is a critical security measure because unsigned apps have not been verified by Apple's developer system, which could leave devices vulnerable to malware or other malicious software. By blocking these apps, iOS and iPadOS ensure that only trusted applications, which have undergone Apple’s stringent review process, can be installed on the device. This helps maintain the integrity of the user environment by allowing only those applications that meet the safety standards set by Apple. This is a key aspect of Apple's approach to security, providing a controlled ecosystem that minimizes risks associated with third-party software.

The other options, while they might touch on aspects of app management, do not contribute to the overarching security framework in the same way. Users can install apps from the App Store regardless of perceived user ratings, as long as they meet other criteria, and authentication for every installation may not be practical or feasible in everyday usage. Therefore, the focus on exclusively permitting signed applications stands out as the primary method for bolstering app security on iOS and iPadOS devices.
