There this example for A also: HIPAA also provides a specific example of pseudonymity. A de-identified dataset may include: A code or other means of record identification to allow information de-identified under this section to be re-identified by the covered entity, provided that: (1) the code or other means of record identification is not derived from or related to information about the individual and is not otherwise capable of being translated so as to identify the individual; and (2) the covered entity does not use or disclose the code or other means of record identification for any other purpose, and does not disclose the mechanism for re-identification.

I think its "d". "Labels: Labels are characteristics that point to an individual. These can be precise, as in a name, or imprecise, such as with an attribute, depending on the context. Labeling people based on an attribute, instead of by name, may make them easier to identify in context. For instance, a man in a business suit may not be identifiable within a large corporate office, but the same man in a business suit may be easily identifiable among sunbathers on a beach."
