Because a media failure caused the data file to be damaged, you want to place the d ata file in a different location while restoring the file. Which option must you consider for this task?（）

• A、using only the RMAN SWITCH command to set the new location for the data file
• B、placing the database in the MOUNT state for the restore and recovery operations.
• C、using an RMAN RUN block with the SET NEWNAME and then the SWITCH command.
• D、configuring two channels: one for the restore operation and the other for the recovery operation
