Which law governs the rights of individuals concerning the privacy of their financial information?

The Graham-Leach-Bliley Act is the correct answer as it specifically addresses the privacy of financial information. Enacted in 1999, this law mandates that financial institutions are required to protect the confidentiality and security of consumers' personal financial information. It established provisions for how financial institutions must handle such information, including rules for disclosing privacy policies to customers and giving them the opportunity to opt-out of having their information shared with non-affiliated third parties.

This law plays a critical role in ensuring consumers' financial information is well protected and that their privacy rights are upheld, making it a cornerstone in the regulation of financial privacy in the United States. The other choices, while significant in their respective areas, do not specifically focus on financial privacy rights in the same comprehensive manner as the Graham-Leach-Bliley Act does.
