Which of the following is an electronic device that may contain evidence?

• A. Wearable tech
• B. Televisions
• C. CDs, DVDs, Blue-ray disks
• D. USB drives

Answer: (C)

Data evidence often lives on storage media, not just inside active devices. Optical discs—CDs, DVDs, and Blu-ray discs—are a common type of removable storage that can hold a wide range of data, from documents and emails to images, videos, and backups. Because they can be found in many environments and can store large amounts of information, they frequently contain evidence that needs to be recovered verbatim. In forensic practice, you’d image the disc with a write-blocked drive to preserve integrity and then analyze the copy for files, metadata, and hidden content. Other options can also harbor data, but optical discs specifically represent portable storage media that can contain substantial information relevant to an investigation.
