Why each option
DIAMETER is a full AAA protocol that natively supports Authentication, Authorization, and Accounting, making it the correct answer for providing AAA Accounting services.
Kerberos is a ticket-based authentication protocol and does not provide accounting or session usage tracking functionality.
SAML is an XML-based federation standard used for single sign-on authentication and authorization assertion exchange, with no built-in accounting capability.
DIAMETER (RFC 6733) was designed as a comprehensive AAA protocol and explicitly supports accounting functions such as session tracking, usage reporting, and billing; it was built as a successor to RADIUS with improved reliability, security, and support for roaming and mobile network environments.
LDAP is a directory access protocol used to query identity stores for authentication and authorization lookups, not for recording or reporting network access usage.
