Which of the following is an example of an unfair trade practice?

Advertising without including required information is indeed an example of an unfair trade practice because it can mislead potential buyers or misrepresent the property being offered. In real estate, it's crucial to provide full and accurate information in advertisements to ensure that consumers have a clear and fair understanding of what is being offered. This transparency helps maintain trust in the real estate market and ensures that all transactions are conducted fairly.

Inadequate advertising that omits essential details can lead to misunderstandings and may cause consumers to make decisions based on incomplete information. It violates ethical standards and regulations that are designed to protect buyers and promote fair dealings in real estate transactions, thus categorizing it as an unfair trade practice.
