Answer
- B Anonymized data can no longer be linked to a person, pseudonymized data only with additional knowledge and remains personal data
Explanation
In pseudonymization, names are replaced by identifiers, for example; with a mapping table the personal reference can be restored. The data therefore remains subject to the GDPR. True anonymization removes the personal reference permanently.
