Option 1: DiameterIdentity
Option 2: OctetString
Option 3: Unsigned32
Option 4: Integer64
Explanation: The correct answer is Unsigned32 because, according to the specifications for SCEF-Reference-ID, it contains an identifier provided by the Service Capability Exposure Function (SCEF) as a unique, non-negative integer value in telecommunications networks.
