Question: In an NR (New Radio) network, when a User Equipment (UE) needs to transfer dedicated LTE information related to V2X sidelink communications using the `ULInformationTransferIRAT` message, what specific type of information is included in the `ul-DCCH-MessageEUTRA`?
Option 1: NR RRC Reconfiguration message for handover preparation
Option 2: E-UTRA RRC MeasurementReport message, SidelinkUEInformation message, or UEAssistanceInformation message related to V2X sidelink communications
Option 3: LTE UE Capability Information for sidelink communication
Option 4: NR Cell Global Identifier (NCI) for initial access
Explanation: This is correct because, according to the specified procedure for transmitting `ULInformationTransferIRAT` messages in the context of V2X sidelink communications, the UE specifically sets the `ul-DCCH-MessageEUTRA` to include information such as the E-UTRA RRC MeasurementReport message, the SidelinkUEInformation message, or the UEAssistanceInformation message. These are directly related to managing and optimizing V2X sidelink communications on the LTE side when transferring information from NR.
