The owners of Underground Airways Ltd.

A is correct because a stock exchange listing would provide Underground with greater market exposure and public confidence than listing on the OTC market. A stock exchange is a regulated and organized market where securities are traded through intermediaries such as brokers. A stock exchange listing can enhance the reputation, visibility, and liquidity of a company’s shares, as well as attract more investors and analysts. An OTC market is a decentralized and less regulated market where securities are traded directly between buyers and sellers, usually through dealers or market makers. An OTC listing may have lower costs and fewer requirements than a stock exchange listing, but it also has less transparency, liquidity, and investor protection. Underground would not be directly involved in the trading of their shares on either market (B), as they would only issue new shares through an IPO and then let the secondary market determine the price and volume of their shares. Underground would be subject to more stringent listing requirements if they chose the stock exchange as compared to the OTC market ©, as they would have to meet higher standards of financial reporting, disclosure, governance, and compliance. If Underground chose to list on the OTC market, there would still be a secondary market available for investors (D), but it would be less liquid and efficient than a stock exchange.
