Which of the following is a reason why PII is regulated?

Establishing a chain-of-custody is relevant in legal and forensic contexts to ensure evidence integrity, not the primary reason for PII regulation.

Increasing the efficiency of databases is a technical design goal and is not a fundamental reason for the regulation of PII.

While PII regulation helps prevent information leaks, this is a consequence of protecting privacy, not the fundamental reason for the regulation itself, which centers on individual rights.

PII (Personally Identifiable Information) is regulated by laws and standards globally, such as GDPR and HIPAA, specifically to protect individuals' privacy rights. These regulations mandate how organizations collect, process, store, and share personal data, giving individuals control over their information and preventing misuse.

PII regulation aims to protect privacy and provide control over personal data, not to discourage anonymity.
