Answer»

The correct option is (b) ESP TRANSPORT mode

The best I can explain: ESP transport mode should be used to ensure the INTEGRITY and confidentiality of data that is exchanged within the same LAN. ESP tunnel mode is comparatively more SECURE and should be used to assure the security of the data within different LANs.
