the question has wrong order for answers, answers should be as follow
A.The SPFILE is copied along with the data files of the pluggable databases (PDBs).
B. The root and the seed database in the container database (CDB) are also duplicated.
C.A backup of pdb1 and pdb5 must exist before executing the command.
D.The duplicate command first creates a backup, and then duplicates the PDBs by using the backup
E. An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.
I think best answer is B and E
A and C may be wrong because not only PDB is copied , CDB and seed also copied and should be in the backup
