Which of the following is considered a permissible free offering in real estate?

The choice of a complimentary dinner at a seminar is considered a permissible free offering in real estate because it is a common marketing practice designed to attract potential clients and provide them with valuable information about real estate in a more relaxed setting. These types of events can help agents build relationships with prospective buyers and sellers, allowing them to showcase their expertise and services in an engaging manner.

Providing such an offering also aligns with industry standards, as it is not directly tied to a financial transaction or obligation. Instead, it serves educational purposes that can benefit consumers. Other options may raise ethical concerns or come across as incentives that could be construed as a violation of regulations, especially if they could influence a consumer's decision inappropriately. Thus, the complimentary dinner at a seminar stands out as an appropriate and compliant choice.
