Sensitive PII is PII used in conjunction with basic PII (for example, SSN card, Driver's License, DOB).

• A. PII used in conjunction with basic PII (i.e., SSN card, Driver's License, DOB)
• B. PII used alone
• C. PII that is publicly available
• D. PII that is not linked to an individual

Answer: (A)

Sensitive PII is data that becomes highly risky when it is combined with basic identifiers. Basic PII includes information that can identify a person by itself, such as name, address, or date of birth. When you add government-issued numbers like a Social Security Number or a driver’s license number, or other highly identifying data, the set becomes sensitive because it greatly raises the potential for identity theft or fraud if disclosed. The example—SSN card, Driver’s License, DOB—illustrates how those identifiers, when linked with other basic PII, escalate risk. Therefore, this description matches the idea that sensitive PII is PII used in conjunction with basic PII. PII used alone, publicly available PII, or PII not linked to an individual do not fit this concept.
