Which type of scientific identification involves devices embedded in the body used for identification?

• A. Surgical implants
• B. Nuclear DNA
• C. Fingerprints
• D. Radiography

Answer: (A)

The idea being tested is identification that relies on a device placed inside the body. When a person has a device implanted—such as a microchip or RFID tag—that carries a unique identifier linked to records, it can be used to positively identify the individual. That makes surgical implants the correct choice. In contrast, nuclear DNA identification uses genetic material, fingerprints rely on external biometric patterns, and radiography is an imaging method to visualize internal structures rather than provide an embedded identification device. This distinction is why implanted devices are the best fit for the description.
