Final answer:
Delivering goods as promised is not a deceptive trade practice; it indicates a transparent business transaction, unlike the other options that involve misleading actions or withholding information.
Step-by-step explanation:
Among the options listed, the one that is not a deceptive trade practice is b. delivering goods as promised. This practice is consistent with honest and transparent business transactions and does not involve deception or misrepresentation. On the other hand, options a, c, and d involve dishonest activities such as falsely guaranteeing loan approval, selling a trade-in vehicle before loan approval, and failing to disclose important information about a vehicle's condition.
The question asks which one of the following is not a deceptive trade practice. Deceptive trade practices involve misleading or dishonest actions taken by sellers. Guaranteeing loan approval that is not final (option a), selling a trade-in before loan approval (option c), and failing to disclose that a vehicle is salvage (option d) are all examples of deceptive trade practices.However, delivering goods as promised (option b) is not a deceptive trade practice. It is the seller fulfilling their obligation and meeting the buyer's expectations. This practice reassures the buyer that they are getting what they paid for.
