Which statement best defines marketplace fraud?

• A. An online marketplace platform refunds a purchase without checking.
• B. A legitimate vendor ships defective goods.
• C. A buyer disputes a payment due to dissatisfaction.
• D. A fraudulent merchant disappears with payments before delivering goods or services; the platform may be liable.

Answer: (D)

Marketplace fraud is when a merchant in the marketplace takes payment for goods or services and then disappears, never delivering what was promised. The platform can be liable because it processes payments and acts as the intermediary, so it has a duty to protect buyers and resolve cases where funds are taken without delivering. The other scenarios describe problems like refunding without verification, shipping defective goods, or a buyer disputing a charge over dissatisfaction—these involve issues or disputes, not deliberate theft by a merchant, so they don’t define marketplace fraud.
