Which of the following is an example of digital evidence?

• A. Fingerprints
• B. DNA sample
• C. Witness statements
• D. Email records and video evidence from devices

Answer: (D)

Digital evidence refers to information stored or transmitted in an electronic format that can be recovered from digital devices or networks. Email records and video evidence captured by devices are classic examples because they are data files created, stored, and retrievable from computers, smartphones, cameras, and other electronics. This makes them digital by nature.

In contrast, fingerprints and DNA are physical or biological traces left on objects or people, not data stored electronically. Witness statements are human accounts or testimony, which is non-digital information unless it has been recorded or stored as a digital file later, but the original form in this context is oral or written testimony rather than electronic data. Digital evidence also requires careful handling to maintain authenticity and chain of custody, including the preservation of metadata, time stamps, and device logs.
