Question: Under what condition(s) can a User Equipment (UE) perform V2X sidelink communication operation when it is in a limited service state, as per 3GPP specifications?
Option 1: If the UE's selected cell on the frequency used for V2X sidelink communication belongs to any Public Land Mobile Network (PLMN).
Option 2: If the UE's serving cell fulfils specific conditions to support V2X sidelink communication in a limited service state, and either the serving cell is on the same frequency or the UE is out of coverage on that frequency.
Option 3: If the UE has a serving cell (RRC_CONNECTED) with any available frequency for V2X sidelink communication.
Option 4: If the UE is in RRC_IDLE mode without considering the serving cell's support for V2X sidelink communication.
Explanation: This option correctly identifies the conditions under which a UE can perform V2X sidelink communication when in a limited service state. Specifically, it highlights the necessity for the serving cell to meet specific V2X support conditions and addresses the scenario where either the serving cell operates on the same frequency as the V2X sidelink communication or the UE is out of coverage on that frequency.
