Which of the following is a permitted free offering?

Providing a complimentary home warranty with listings can be considered a form of inducement to attract clients, which may not be permitted under certain real estate regulations. Such offerings could be seen as affecting the terms of the transaction rather than enhancing a buyer's experience in an educational setting.

Offering a coupon for discounted commission could be interpreted as an attempt to influence the client's decision regarding listing services. This form of compensation can blur the lines of ethical practices in real estate, as it directly affects the financial terms of the transaction rather than providing general information or value.

While providing free use of a moving van may seem beneficial, it can be viewed as a promotional incentive tied to the listing process. Such offerings may violate guidelines that prohibit incentives that could be construed as influencing a buyer's or seller's choice in a real estate transaction.
