A. They can be written only to disk. - not only
B. They must be written to media. - not must
C. They can be created by using the RMAN CONFIGURE command to specify duplexing before taking a backup. - true
D. They can be created only by using the COPIES option of a BACKUP command. - not only
E. They can be written to media. - true
CE are correct:
https://docs.oracle.com/en/database/oracle/oracle-database/18/bradv/configuring-rman-client-advanced.html#GUID-2A285F87-552A-4F36-A5B9-F25A69611B4B
C, E
In most cases, the easiest method of duplexing backup sets is to use BACKUP... COPIES or CONFIGURE ... BACKUP COPIES to duplex backup sets.
RMAN can duplex backups to either disk or tape, but cannot duplex backups to tape and disk simultaneously.
I think CE.
D is wrong because of "only"
