How would you recover from the loss of the redo log member?

Redo log files are multiplexed in your database. The disk in which you have one of the redo

log members is highly fragmented. In the process of defragmentation you lose the redo log
member, which is not a member of the current group. How would you recover from the loss
of the redo log member?

A.
SMON would automatically restore the lost file.

B.
You would need to restore the missing log file by copying one of the remaining files
from the same group.

C.
You would need to use Recovery Manager (RMAN) to restore the lost redo log
member.

D.
You would need to use flashback technology to restore the lost redo log member.

E.
You would need to restore the whole database from the last backup.

F.
You would need to restore the file from the last full database backup.
