You are managing an Oracle Database 11g database. You want to take a backup on tape drives of the USERS tablespace that has a single data file of 900 MB. You have tape drives of 300 MB each. To accomplish the backup, you issued the following RMAN command:RMAN BACKUPSECTION SIZE 300M TABLESPACE users;Identify the appropriate configuration to accomplish faster and optimized backups using the above command.()A. The SBT channel must be configured, with the MAXPIECESIZE set to 300 mb.B. The SBT channel must be configured, with the parallelism setting for the SBT devices set to 3.C. The COMPATIBLE initialization parameter for the database instance must be set to at least 10.0.D. The SBT channel must be configured, with the default parallelism setting for the SBT devices set to 1
