Personally Identifiable Information (PII) refers to data that can be used to trace an individual's identity, such as:

• A. Information that can be used to trace an individual's identity such as name, social, DOB, fingerprints, etc.
• B. A type of encryption key.
• C. Publicly available information about individuals.
• D. Non-identifying business details.

Answer: (A)

PII is data that can be used to identify a specific person. The option listed includes direct identifiers like name, a unique government ID (such as a Social Security number), date of birth, and biometric data (fingerprints). These are precisely the kinds of details that, alone or in combination with other data, can trace someone’s identity. That alignment with identifying information is why this is the best choice.

The other options miss the defining point: an encryption key is a cryptographic tool, not identity data; publicly available information about individuals can be about them but isn’t, by itself, what makes data PII; and non-identifying business details do not reveal who a person is.
