D Correct answer
Explanation

DB2 9 supports SERVER, SERVER_ENCRYPT, CLIENT, and CLIENT_ENCRYPT authentication types. DCS (Database Connection Services) is not a valid authentication method - it's a facility for connecting to non-DB2 databases (like Oracle, SQL Server) through DRDA, not an authentication type.
