Explanation

Kerberos is the native authentication protocol of Microsoft Active Directory. When sponsors must authenticate using Kerberos tickets, Active Directory is the only identity source in this list that supports Kerberos. AD uses Kerberos v5 as its primary authentication mechanism for domain-joined environments. LDAP (option D) uses LDAP bind operations for authentication, not Kerberos. SAML (option B) is a federated SSO protocol that uses assertions, and RADIUS (option A) uses the RADIUS protocol - neither natively implements Kerberos.
