Question: In E-UTRA, what is the primary purpose of the `resumeWithSCG-Config-r16` parameter in relation to an NR (New Radio) Secondary Cell Group (SCG)?
Option 1: To indicate UE support for SCG configuration via NAS (Non-Access Stratum) signaling.
Option 2: To trigger the release of all ongoing SCG configurations upon RRC connection resume.
Option 3: To define whether the UE supports (re-)configuration of an NR SCG within the RRCConnectionResume message.
Option 4: To notify the network about the UE's preferred SCG configuration for handover scenarios.
Explanation: This option correctly reflects the purpose of `resumeWithSCG-Config-r16` as it highlights the parameter's role in signaling UE support for the (re-)configuration of an NR Secondary Cell Group directly through the RRCConnectionResume message, key to efficient radio resource management in E-UTRA networks during connection resume procedures.
