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

Using deceptive advertisements to mislead consumers exemplifies an unfair practice because it violates consumer trust and promotes misinformation. This type of advertising does not provide accurate information about the products being sold and can manipulate consumers into making purchases based on false or misleading claims. It undermines the principles of honesty and transparency that are fundamental to fair competition and consumer protection.

Accurate advertising represents fair practices by providing consumers with the correct information necessary to make informed purchasing decisions. Providing lifetime warranties is also a fair practice, as it offers consumers additional security and assurance about the products they buy. Similarly, offering discounts to returning customers encourages loyalty and is a common business practice that benefits both consumers and businesses.
