Explanation

Data anonymization (D) directly protects data confidentiality by removing or masking personally identifiable information (PII), ensuring that even if data is exposed or shared across databases, individuals cannot be identified.

A (Logical data model) describes how data is structured and related - it's a design artifact, not a security control.
B (Data normalization) reduces redundancy and improves data integrity, but has no bearing on who can read or identify sensitive data.
C (Data catalog vocabulary) standardizes data terminology and metadata definitions across an organization - useful for governance, not confidentiality.

Memory tip: Think "anonymization = anonymity." The word itself contains the goal - making data anonymous so it can't be traced back to a person, which is the essence of confidentiality protection.
