Final answer:
ABC company's promise to Todd for a full refund if the mountain bike does not perform as expected is a money-back guarantee, an explicit reassurance of product quality.
Step-by-step explanation:
The promise that ABC company made to Todd, which stated that he would receive a full refund if the mountain bike did not perform as expected, would be classified as a money-back guarantee. This is an agreement that functions as a promise of quality and is a strategy used by companies, especially those selling goods through mail-order catalogs or the web where physical examination of the product prior to purchase is not possible.
Such guarantees serve to reassure the customer and encourage purchases by providing a form of risk reduction. Guarantees, warranties, and service contracts are all forms of explicit reassurance provided by sellers to instill confidence in their products.
