Which of the following statements about PII is true?

The statement that Personal Identifiable Information (PII) includes information that can be used to trace or identify a person's identity is accurate. PII encompasses a range of data that, when combined, can uniquely identify an individual. This can include names, addresses, social security numbers, email addresses, phone numbers, and other identifiers. Understanding that PII is crucial for privacy and security reasons helps to recognize how personal information can affect individuals if mishandled or exposed.

The other options present misunderstandings about PII. Some may incorrectly assert that PII requires financial data to identify individuals or that it is solely used for marketing. Additionally, PII certainly includes names and addresses, making the claim that it does not contain such information incorrect. Therefore, the statement about PII's role in tracing and identifying individuals best captures its definition and significance.
