• A. StegSpy
• B. Tasklist
• C. OpenStego
• D. Suricata

Answer: (C)

OpenStego is built for hiding data inside other files and for embedding watermarks to mark ownership. Data hiding, or steganography, lets you conceal information within a cover file, while watermarking adds a tag that identifies the file’s owner or origin. That watermark can be carried on in distributed copies, so if an unauthorized copy surfaces, you can extract the watermark to help prove who distributed it or who owns the content. The other tools play different roles: StegSpy is for detecting hidden data in files (steg analysis) rather than embedding watermarks; Tasklist is just a Windows process list, and Suricata is a network IDS/IPS, not related to file watermarking.
