Option 1: A list of candidate UEs and Member UE filtering criteria
Option 2: A list of target UEs in the form of GPSIs or UE IP addresses, along with at least one Member UE filtering criterion
Option 3: The subscribed Member UE filtering criteria and a request to update parameters for selecting candidate UEs

Explanation: According to the text, the AF provides a list of target UEs in the form of GPSIs or UE IP addresses, along with at least one Member UE filtering criterion as part of the service operation parameters to assist in candidate UEs selection. This information is used by the NEF to retrieve and consolidate data from other 5GC NFs to derive a list of candidate UEs based on the AF's filtering criteria.
