Explanation

This is a subtly worded question. True anonymization (D) would seem like the obvious answer - irreversibly removing all identifiers. However, in practice, true anonymization is extremely difficult to achieve and verify. Pseudonymization (B) replaces direct identifiers with artificial identifiers (pseudonyms), and when done properly with key separation, it is the recognized and practical standard for de-identifying personal data under frameworks like GDPR. The exam key selects pseudonymization as the best realistic method. Encryption (A) and hashing (C) are reversible or still tied to identity, so they do not convert data to non-personal information.
