Which is a PII law specifically for financial institutions?

The correct answer is that the Gramm-Leach-Bliley Act (GLBA) specifically addresses the protection of personally identifiable information (PII) within the financial services sector. Enacted in 1999, the GLBA requires financial institutions to explain their information-sharing practices to their customers and to safeguard sensitive data. This law stands out for its emphasis on consumer privacy and the requirement that financial institutions provide a privacy notice to individuals about their practices concerning the collection and sharing of personal financial information.

In contrast, the other options do not serve the same specific purpose as the GLBA. The Gramm-Leach-Bliley Act is the only legislation among the choices that directly regulates how financial companies handle PII. The Payment Card Industry Data Security Standard (PCI DSS) relates to the security of credit card transactions and protecting cardholder data but is not a law enacted by Congress, instead it is a set of security standards. Other options mentioned may be similar terms but do not pertain specifically to financial institutions or PII in the same statutory manner.
