Explanation

'dd' (disk dump / data duplicator) is a native Unix/Linux utility that performs low-level, sector-by-sector copying of storage media, producing a forensic bit-stream image that includes every byte - including deleted files and slack space. 'mcopy' (A) is an mtools command for copying to/from FAT-formatted media. 'image' (B) is not a standard Linux utility. 'MD5' (C) is a hashing algorithm used to verify image integrity, not to create the image.
