Express warranty was breached.
Option a
Explanation:
An express warranty is a contract by a seller to provide replacement or repair within a specified period of time for a defective product, service or component. In accordance with the federal Magnuson-Moss Warranty Act, if an item is sold for < $15 a company must make written express warranty.
For compliance with the Magnuson-Moss Warranty Act, if a product is sold for more than 15 million, a manufacturer must provide a formal specific warranty.
Description of a product or service mentioned in the commercial will set a clear promise as a precedent.
An implicit promise can take effect in the absence of expressed guarantees.
