C Correct answer
Explanation

DB2 9 supports several authentication types: SERVER (database authenticates), CLIENT (client authenticates), SERVER_ENCRYPT (server with encrypted passwords), and KERBEROS. DCS (Database Connection Services) is not an authentication method - it's a feature that enables access to non-DB2 databases like DB2 for z/OS through DRDA connectivity.
