option 4: The UE obtains them from the PCF via local configuration.
option 5: The UE uses the implementation of FRER in its operating system.
### Response:
option 1: The UE determines them based on URSP rules and matched traffic descriptors.
explanation :When URSP is used to establish two redundant PDU Sessions, the UE differentiates duplicated traffic by using distinct traffic descriptors in distinct URSP rules.
