- Option 1: Information Center – This refers to a place where information is provided. It has nothing to do with buyer’s responsibilities or warnings.

- Option 2: Unfair Trade Practices – This means dishonest or fraudulent business dealings. It is the opposite of what “let the buyer beware” stands for, as it refers to sellers breaking rules, not buyers being careful.

- Option 3: Caveat Emptor – This is Latin for “Let the buyer beware.” It means it’s the buyer’s responsibility to check the quality and suitability before buying a product.

- Option 4: Buyer Kingdom – This is not a valid term in business or consumer rights. It doesn’t relate to buyer caution or protection.
