Configuration profiles, deployed via MDM or manually, allow IT administrators to restrict apps on a device by setting policies such as blocking the App Store, preventing app removal, or allowing only specific apps (e.g., via an allow list). These profiles are highly customizable for security and compliance. Activation Lock (option A) secures device reactivation, not app restrictions. Find My (option C) and iCloud (option D) are user-focused features without app restriction capabilities. The Apple Platform Deployment Guide details configuration profiles' role in app management.
