Personally Identifiable Information (PII) refers to data that can be used to identify, contact, or locate a single person, or to identify an individual in context. A full name and date of birth are classic examples of PII because they can directly identify a person. Other options listed may relate to a person's life but do not specifically and directly identify an individual in most contexts.
Reference: The definition and examples of PII are part of data privacy topics covered under the CompTIA IT Fundamentals, which discusses security measures and identification data types.
