Victor works as a professional Ethical Hacker for SecureNet Inc. He wants to use Steganographic file system method to encrypt and hide some secret information. Which of the following disk spaces…

Hidden partitions exist physically on the disk but are omitted from the partition table visible to the operating system, making them a primary steganographic storage location for concealed data. B: Slack space is the unused byte range between the logical end of a file and the end of its last allocated cluster, which steganographic tools exploit to embed hidden data without altering visible file contents. D: Unused sectors are not allocated to any active file system structure and are typically skipped by the OS, providing another location where steganographic file systems can store secret information undetected.

'Dumb space' is not a recognized term in disk forensics or steganographic file system methodology and does not correspond to any real disk structure.
