I agree with both of you, your informations are correct one, according to oracle “D” is the best answer. I also found the below illustartion from internet, it might be helpful in justfying the answer.

1.
SQL>select FILE_ID,FILE_NAME,TABLESPACE_NAME from dba_data_files;

FILE_ID FILE_NAME TABLESPACE_NAME
———- ———————————————- ———————-
4 /u01/app/oracle/oradata/test0910/users01.dbf USERS
3 /u01/app/oracle/oradata/test0910/undotbs01.dbf UNDOTBS1
2 /u01/app/oracle/oradata/test0910/sysaux01.dbf SYSAUX
1 /u01/app/oracle/oradata/test0910/system01.dbf SYSTEM
5 /u01/app/oracle/oradata/test0910/example01.dbf EXAMPLE

2.backup datafile users01.dbf
RMAN> backup tablespace users;

Starting backup at 13-SEP-13

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:15
Finished backup at 13-SEP-13

3. delete datafile users01.dbf
[oracle@rtest ~]$ rm -rf /u01/app/oracle/oradata/test0910/users01.dbf
[oracle@rtest ~]$ ls /u01/app/oracle/oradata/test0910/users01.dbf
ls: /u01/app/oracle/oradata/test0910/users01.dbf: No such file or directory

4. shutdown abort and startup the instance
SQL> shutdown abort;
ORACLE instance shut down.

SQL> startup
ORACLE instance started.

5. running repair failure will return error
RMAN> repair failure ;
using target database control file instead of recovery catalog
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of repair command at 09/13/2013 11:20:04
RMAN-06954: REPAIR command must be preceded by ADVISE command in same session

6. run advice failure will return error as well
RMAN> advise failure;

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of advise command at 09/13/2013 11:20:59
RMAN-07211: failure option not specified

—Correct sequence
7. Run LIST–>ADVISE–>REPAIR

RMAN> list failure;

List of Database Failures
=========================

Failure ID Priority Status Time Detected Summary
———- ——– ——— ————- ——-
122 HIGH OPEN 13-SEP-13 One or more non-system datafiles are missing

RMAN> advise failure;

Mandatory Manual Actions
====================================

Optional Manual Actions
=======================
1. If file /u01/app/oracle/oradata/test0910/users01.dbf was unintentionally renamed or moved, restore it
