• A
  72% (21)
• B
  21% (6)
• C

Explanation

Restoring an IP phone to factory defaults wipes all user-configured data and returns every parameter to its out-of-the-box state (A), which is precisely what "factory default" means by definition. D is correct because holding the Home button for 10 seconds on the login screen is the standard hardware-level reset procedure used when you can't access the phone's settings menu (e.g., forgotten password).

B is wrong because contacts and call history are user-generated data - they are stored locally and get erased during a factory reset. C is wrong for the same reason: imported ringtones, language packs, and wallpapers are user-added customizations that do not survive a reset; only the vendor's pre-loaded defaults remain.

Memory tip: Think of "factory default" literally - the phone returns to exactly the state it was in when it left the factory. Nothing you added survives. The Home button hold (D) is the "locked-out technician's escape hatch" - useful when the normal menu is inaccessible.
