Personal data includes information such as name, address, phone number, birth date, sex, birth weight, units, and SSN. These are all examples of specific pieces of information that can be considered personal data. The other options mentioned in the question, "All members of a family" and "A & B only" are not accurate representations of what personal data includes. Therefore, the correct answer is "Name, address, phone number, birth date, sex, birth weight, units, SSN."
