Your database runs in NOARCHIVELOG mode， and is backed up every night using RMAN scripts. However， last night your assistant DBA performed a manual operating system backup， instead of running the scripts. Today your database crashed and you now want to use the backups from last night. What do you need todo？（）
A:You need to perform the restore and recover operations manually, because the backup was made manually. 
B:First you need to resynchronize the catalog with the control file, and then you can use RMAN to recover the database. 
C:First you need to add the backup to the catalog using the CATALOG command, and then you can use RMAN to recover the database. 
D:You can just use RMAN and recover the database, because RMAN automatically updates the catalog with the backup information.
