Which of the following is a common deceptive practice?

Bait and switch tactics represent a common deceptive practice in consumer transactions. This approach involves advertising a product at a low price to attract customers but then persuading them to purchase a different, often more expensive item once they show interest. This practice misleads consumers about the availability and pricing of products, violating principles of fair trading and consumer rights.

In contrast, clear advertising of all product features, transparent pricing, and offering discounts for early purchase are practices that promote honesty and transparency in commerce. Clear advertising helps consumers make informed decisions by providing accurate information about what they are buying. Transparent pricing ensures that consumers can easily understand the costs involved without hidden charges. Offering discounts to encourage early purchase is a legitimate marketing strategy aimed at incentivizing sales without misleading consumers.
