Anonymization is fundamentally about ensuring that personal data cannot be linked back to an individual, thereby protecting their identity and privacy. In this context, the correct option reflects the process of removing all personal identifiers from data sets. Once this removal occurs, the data loses its ability to point back to a specific person, making it impossible for anyone to ascertain the identity of the individual to whom the data originally belonged.

This process is critical in data privacy because it allows organizations to utilize data for analysis and insights without infringing on individual privacy rights. Anonymization is particularly important in regulatory frameworks like the General Data Protection Regulation (GDPR), which emphasizes the need to protect personal data while still allowing for its use in research and statistical analysis.

In contrast, the other options involve practices that either maintain a link to individuals (such as creating unique identifiers) or do not specifically relate to the act of safeguarding personal data against identification (like sharing data with third parties or aggregating data). Therefore, they do not accurately capture the essence of anonymization.
