In advertising or marketing a time share interest that might include free prizes, which of the following must be clearly disclosed?

When advertising or marketing a timeshare interest that includes free prizes, it is essential to clearly disclose all relevant information to potential buyers to maintain transparency and ethical practices. This includes the retail value of the gift, as it helps the consumer understand the worth of what they are being offered. Additionally, the conditions under which the gift is offered must be disclosed so that consumers are aware of any requirements or limitations that come with accepting the gift. If a prize involves any randomness, the odds of winning should also be shared to provide a clear picture of the likelihood of receiving that prize.

By requiring the disclosure of all these elements, the intent is to protect consumers from misleading or deceptive advertising practices. Failing to disclose any of this information could lead to misunderstandings and may not comply with legal advertising standards, which is why all elements of A, B, and C are necessary to inform potential buyers accurately. Thus, the correct choice encompasses the comprehensive requirement for clear disclosure in such marketing practices.
