A mobile security training scenario describes a user at an airport connecting their phone to a public USB charging station. The phone displays a 'Trust this Computer?' dialog. The user taps 'Trust.' What has the user consented to?

• A.Full USB data access from the connected computer/charging station to the phone, including the ability to install apps (ADB access), access the file system, and potentially backup device data
• B.File transfer over MTP, and nothing else (ADB access, backup, and app installation each need a separate developer toggle the user has to enable in Settings), a toggle the charging station has no way to reach on its own
• C.Access to photos and videos through the PTP profile, and the dialog scopes the grant to the camera roll (documents, backups, and application data stay out of reach)
• D.Charging alone, and the dialog is a courtesy prompt the platform shows on any first connection (data access needs a second confirmation)
