Which of the following regulations are aimed at protecting individuals at the state level?

The correct answer is A, Blue-sky laws. Blue-sky laws are state-level securities regulations designed to protect investors from fraud and unethical practices in the sale of securities. Each state has its own securities regulator and rules governing the registration of securities, broker-dealers, and investment advisers operating within that state.

Step-by-step, Blue-sky laws require securities offerings to be registered at the state level unless exempt, and they also mandate disclosure and anti-fraud provisions to ensure investors receive accurate information. These laws complement federal regulations but specifically focus on local investor protection.

Choice B, the Truth in Lending Act, is a federal law that governs disclosure of credit terms for consumers, not securities regulation. Choice C, Regulation T, is also federal and issued by the Federal Reserve to regulate margin requirements for securities purchases. Choice D, Know-your-customer (KYC) standards, are industry rules enforced by FINRA and other regulators, but they are not state-specific laws.

Thus, the only regulation aimed specifically at protecting individuals at the state level is Blue-sky laws, making Answer A correct.
