What constitutes bait and switch advertising?

Answer: D — All of the above

Bait and switch advertising involves misleading customers by advertising a specific product at a low price, then pressuring them to purchase a higher-priced item instead. In this context, all the listed actions — switching a customer to a different model without explanation, disparaging the advertised product, and accepting a deposit only to switch the customer to a higher-priced vehicle — exemplify different facets of this deceptive practice. When a dealership promotes a vehicle at an attractive price but then does not have that vehicle available or implies that it is of lesser quality, they are engaging in deceptive tactics. Similarly, accepting a deposit under false pretenses and then pushing the customer towards a more expensive option further exemplifies unethical behavior associated with bait and switch tactics. These practices undermine consumer trust and violate advertising laws, making a comprehensive understanding of all these elements critical for ethical marketing and sales in the auto industry.
