Question: In a 5G system, when using Mission Critical Services (MC services) over 5G Multimedia Broadcast/Multicast Service (MBS), where can Forward Error Correction (FEC) be optionally applied to protect transmissions?
Option 1: Exclusively by the User Equipment (UE) for all MC services
Option 2: Either by the MBS Task Force (MBSTF) if required by the MC service server, or directly by the MC service server itself
Option 3: Only by the 5G Core Network as part of Quality of Service (QoS) management
Option 4: Mandatory application at the Radio Access Network (RAN) for all broadcast/multicast sessions
Explanation: This is correct because FEC support is optional and can be applied in two ways for MC services over 5G MBS: either the MBSTF can apply it if specifically requested by the MC service server, or the MC service server can directly apply FEC itself, allowing for tailored QoS management based on the service's requirements.
