Face print and fingerprint are definitely #2, something you have. Both can be easily copied. #3 would be your DNA sequence perhaps.
Similarly, SMS authentication is not #2. The mapping of your phone number to your phone is not something you possess, it is sitting in some phone company system somewhere and it can be changed.
