Which item is an example of 'Something you are'?

• A. Password
• B. Cookies
• C. RFID badge
• D. Biometric data

Answer: (D)

The concept being tested is authentication factors and which category a given method falls into. Biometric data fits the "something you are" category because it uses inherent physical or behavioral traits—like a fingerprint, iris pattern, facial features, or voice—unique to the individual to verify identity. Unlike a password (something you know) or an RFID badge (something you have), biometric data relies on an intrinsic part of you, making it harder to share or transfer. While this method offers convenient, hands-free access, it also brings privacy considerations and potential spoofing risks, so secure storage and anti-spoofing measures are important.
