单选题The database is running in ARCHIVELOG mode and the FORMAT option is not configured in RMAN for disk backups. You configured the flash recovery area location and size by using the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE initialization parameters. Which statement is correct in this scenario？（）A
If the FORMAT option to the RMAN BACKUP command is specified， then RMAN creates backup pieces and image copies in the flash recovery area with names in the Oracle Managed Files （OMF） format.B
