What must be included in an advertisement for an annuity product displayed on a highway billboard?

The correct answer focuses on the requirement that a representative selling annuity products must clearly identify themselves to maintain transparency and ensure that consumers can verify their credentials. It’s important for accountability that the person behind the advertisement is known, as this fosters trust and helps consumers understand who they are dealing with.

In the context of regulatory standards for advertising financial products like annuities, including the representative's name allows potential customers to conduct their own due diligence. This aligns with consumer protection laws that emphasize the importance of clear and honest communication in marketing financial services.

The other elements of an advertisement, such as product features, the licensing authority, or employer information, while potentially relevant in other contexts, do not specifically highlight the individual’s responsibility in this scenario. Ensuring that the representative's name is prominently displayed helps establish a direct connection and reassurance to potential clients regarding whom they can contact for additional information or to pursue a purchase.
