I feel like there could be four states, but I need to double-check how the transitions are defined in the diagram.

I think there are three states based on similar practice questions we did, but I might be mixing it up with another diagram.

Hmm, looks like we need to 'press' the right buttons to get the correct answer. I bet the developers had a 'finger' in designing this system.

Hold on, are we sure the 'Password OK' and 'Fingerprint OK' states are really distinct? I'm going to go with C) 3 just to be safe.
