Adam is working as a Database Administrator （DBA） for TeleSoft Corporation. His database is running in the ARCHIVELOG mode. During database startup， he discovers that one of the disks crashed， resulting in the permanent loss of a read-write USERS tablespace. The USERS01.dbf datafile belongs to the USERS tablespace and is 500 MB in size. He needs to recover the USERS tablespace from the backup. While reviewing the backup details， he discovers that the most recent available backup is five days old. This backup was taken when the USERS tablespace was read-only. After correcting the hardware problem that caused the failure， what should Adam do to recover the USERS tablespace？（）

A、 Restore the USERS01.dbf file from the backup， and open the database using the STARTUP command.

B、 Restore the USERS01.dbf file using the RECOVER TABLESPACE command， and open the database using the ALTER DATABASE OPEN statement.

C、 Restore the USERS01.dbf file from the backup， recover the USERS tablespace using the RECOVER TABLESPACE command， and open the database using the ALTER DATABASE OPEN statement.
