What must John Bargas of Buywell Realty list in the phone book?

John Bargas must list "Buywell Realty" in the phone book because real estate regulations typically require agents and brokers to provide their firm name prominently when advertising their services. This requirement is in place to ensure that consumers can easily identify the brokerage that is responsible for the real estate activities and transactions. The focus on the brokerage name helps maintain a level of professionalism and accountability within the industry. Listing the firm name also aligns with standard advertising practices stipulated by regulatory bodies, which aim to protect consumers by ensuring they are aware of who they are dealing with in a real estate context.

Each of the other options would not meet the regulatory requirements for public listings. For instance, using a personal name or a variation of it does not fulfill the obligation to identify the brokerage. Similarly, listing a most active agent or a combination of names may not adequately represent the business entity as required. Therefore, including "Buywell Realty" in the phone book is essential for compliance and proper representation in the marketplace.
