tested: backup pluggable database "cdb$root". the quotes due to the $ symbol. it backups only the root container files (no pdb datafiles).
tested CD: both incorrect
Tested b: correct
A is not correct due to the "must". you can connect to cdb and distinguish between tbs with same name in different pdbs with qualifying RMAN> BACKUP TABLESPACE pdb1:system, pdb1:sysaux, pdb1:users, pdb2:system;

Which two are true about RMAN duplexed backup sets? (Choose two.)
