Explanation:

The Securities Act of 1933 requires that new securities must be recorded with the Securities and Exchange Commission (SEC). When registered representatives are offering stocks to their clients, they are required to adhere to the prospectus delivery if the IPO (initial public offering) or APO (additional public offering) after up to 90% of the event.

No IPO or APO is mentioned in the question, but only options A and B refer to securities that could have been recently issued. Since option A is about a municipal bond (industrial revenue bonds are considered municipal bonds), and municipal bonds are not included in the Securities Act of 1933, then we can eliminate that option.

The only possible option we have left is option B. Open end investment stocks are basically a constant IPO since every time an investor buys a stock, it is creating a new stock, e.g. when you invest in a mutual fund you are creating new mutual fund stocks. It doesn't matter if the mutual fund only invests in US treasuries.
