The correct answer is B, Investment Advisers Act of 1940. This Act specifically regulates individuals and firms that provide investment advice for compensation, making it directly applicable to the scenario described in the question.
Step-by-step, the Investment Advisers Act of 1940 requires investment advisers to register with the SEC or state regulators, depending on their assets under management. It also imposes fiduciary duties, meaning advisers must act in the best interests of their clients, provide full disclosure of conflicts of interest, and adhere to anti-fraud provisions.
Choice A, the Securities Act of 1933, focuses on the initial issuance of securities, requiring registration of new securities offerings and full disclosure to investors. It does not regulate investment advisers. Choice C, the Investment Company Act of 1940, governs investment companies such as mutual funds, not individuals providing advice. Choice D, the Securities Acts Amendments of 1975, primarily enhanced the regulatory framework of markets and expanded the authority of the SEC, but did not establish adviser registration requirements.
Therefore, the law that directly addresses registration and regulation of investment advisers receiving compensation is the Investment Advisers Act of 1940.
