Explanation

A low-level format (A) overwrites every sector of the hard drive with zeros or random data (sometimes multiple passes), making data recovery extremely difficult or impossible even with forensic tools. This is the industry-accepted method for secure data sanitization. Option B (manually deleting data in the OS) only removes file system references - the underlying data remains recoverable with undelete tools. Option C (deleting the partition and reformatting) removes partition tables and file system structures but does not overwrite the actual data on the disk. Option D (standard format) only clears the file system metadata without overwriting the raw data sectors.
