Question: Under what condition related to SystemInformationBlockType2 must be met for a UE connected to 5GC to initiate a procedure for Control Plane (CP) transmission using PUSCH with PUR (Priority Uplink Resource allocation)?
Option 1: SystemInformationBlockType2 includes `cp-PUR-EPC` and the UE's UL data size is smaller than the maximum supported TBS.
Option 2: SystemInformationBlockType2 includes `cp-PUR-5GC` and the resulting MAC PDU size is within the UE's category-based maximum supported TBS.
Option 3: SystemInformationBlockType2 includes `up-PUR-EPC` and the UE has sufficient power for transmission.
Option 4: SystemInformationBlockType2 does not include any PUR-related indicators, but the network has previously acknowledged PUR capability.
Explanation: For a UE connected to 5GC to initiate CP transmission using PUSCH with PUR, SystemInformationBlockType2 must include `cp-PUR-5GC`, and the resulting MAC PDU size must be within the UE's category-based maximum supported TBS for successful transmission.
