Step-by-step explanation:
The correct answer is (d) A special license is needed to market timeshares.
Timeshare sales involve selling fractional ownership or the right to use a property for a specified period each year. Since this is a specialized area of real estate, agents must hold a special license to market timeshares.
For example, in the United States, many states require a specialized license or registration to sell timeshare interests. This ensures that agents have the necessary knowledge and understanding of the unique regulations and requirements associated with timeshare sales.
