C. If the flash recovery area location is configured using the DB_RECOVERY_FILE_DEST initialization parameter, then the RMAN backup of Oracle managed datafiles (OMF) only will go to the flash recovery area by default.
D. If no other destination is configured for recovery files, then RMAN places the control file autobackups in the flash recovery area by default.
