Question: In which scenario does a User Equipment (UE) choose the substate 5GMM-DEREGISTERED.NO-SUPI?
Option 1: When N1 mode is enabled and the UE has no valid subscriber data available.
Option 2: When N1 mode is disabled and the UE has valid subscriber data available.
Option 3: When the UE is in idle state and has a valid USIM.
Option 4: When the UE is in connected state and has an invalid USIM.
Explanation: The substate 5GMM-DEREGISTERED.NO-SUPI is chosen by the UE when N1 mode is enabled, indicating that the UE does not have a valid subscriber data available. This could be due to various reasons such as the absence of a USIM, an invalid USIM, or an invalid entry in the list of subscriber data corresponding to the SNPN identity.
