In Recovery Manager (RMAN), you are taking image copies of the data files of your production database and rolling them forward at regular intervals. You attempt to restart your database. After a regular maintenance task, you realize that one of the data files that belongs to the USERS tablespace is damaged and you need to recover the data file by using the image copy. Because a media failure caused the data file to be damaged, you want to place the data 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
