Apple Configurator for Mac resolves boot issues. The Apple Configurator User Guide states, "If an iPad is stuck on the Apple logo, connect it to a Mac running Apple Configurator to perform a full restore." Option A doesn't exist, and B and C don't address this issue directly. Reference: Apple Configurator User Guide, "Restoring Devices" section. Apple Platform Deployment Guide, "Troubleshooting Devices" section.
