Apple Configurator is a macOS application requiring a Mac computer to run, used for supervising and configuring iOS/iPadOS/tvOS devices via USB. An MDM solution (option A) can complement it but isn't required. User acceptance (option C) isn't needed, as it's an administrative tool. A VPN configuration (option D) is unrelated. The Apple Platform Deployment Guide specifies a Mac as the platform for Apple Configurator.
