Explanation
Data anonymization removes or replaces personally identifiable information (PII) so that individuals cannot be identified from the data - effectively separating the record from the person. This is its defining characteristic. Data encryption (C) protects data in transit or at rest but the data remains linked to the individual; the link is just obscured by encryption. Data backup (A) is a availability/resilience practice with no privacy-separation function. Data aggregation (D) combines data from multiple sources, which can actually increase re-identification risk rather than reduce it. Anonymization is the correct privacy-by-design technique for de-linking identity.
