Explanation

CHKDSK (Check Disk) is a Windows command-line utility that scans the file system and file system metadata for errors, identifies bad sectors, and attempts to recover readable data from bad sectors. Running 'chkdsk /f' fixes file system errors, and 'chkdsk /r' locates bad sectors and recovers readable data. It is the correct tool for diagnosing and repairing drive integrity issues. XCOPY (B) is a file/directory copying utility. FDISK (C) is a legacy partitioning tool used to create or delete partitions - it does not check or repair file systems. FORMAT (D) erases all data on a volume and creates a new file system - it does not repair an existing one.
