Which of the following statements about the protection of service-based interfaces (SBIs) is FALSE?

• A.The OAuth 2.0 framework is used to secure the communication between network functions within a PLMN at the network layer.
• B.The security edge protection proxy (SEPP) handles the security of inter-domain SBIs and protects the interaction between network functions in different PLMNs.
