You are administering a multitenant container database (CDB) CDB1 that is running in ARCHIVELOG mode and contains pluggable databases (PDBs), PDB_1 and PDB_2. While opening pdb_1, you get an error: SQL> alter pluggable database pdb_1 open; ORA-01157: cannot identify/lock data file 11-see DBWR trace file ORA-01110: data file 11: `/u01/app/oracle/oradata/cdb1/pcb_1/example01.dbf` To repair the failure, you open an RMAN session for the target database CDB$ROOT. You execute the following as the first command: RMAN> REPAIR FAILURE; Which statement describes the consequence of the command? 

Answer options:

A. The command performs the recovery and closes the failure.
B. The command produces an error because RMAN is not connected to the target database pdb_1.
C. The command produces an error because the ADVISE FAILURE command was not executed before the REPAIR FAILUER command.
D. The command executes successfully, performs recovery, and opens PDB_1.
