单项选择题You discover that the ms db database on a SQL Server 2005 computer is corrupt and must be restored. Databases are backed up daily. The database backup files are written to a network share， but the file names do not clearly indicate which databases are in each file. You need to locate the correct backup file as quickly as possible. The first file in the list isnamed DB Backup.bak. Which Transact-SQL statement should you use？（）

A.RESTORE LABELONLYFROM DISK = N\\Server1\Backup\DB Backup.bak
