What are the two types of warranties for commercial products and services?

The two types of warranties for commercial products and services are implied warranties and express warranties. Implied warranties are those that are automatically included in a transaction by law, regardless of whether they are explicitly stated. They assure that the product will function as a reasonable person would expect, covering aspects like merchantability and fitness for a particular purpose.

Express warranties, on the other hand, are clearly articulated promises made by the seller about the quality or nature of the product, either through written statements, descriptions, or demonstrations. These warranties provide assurance that the product will meet certain standards.

In contrast, the other options that mention "written warranties" or "oral warranties" either fail to cover the broader legal concept of warranties or confuse the formal aspects of warranty communication with the types that exist under commercial law. Therefore, the combination of implied and express warranties best represents the framework used to protect consumers and regulate commercial transactions.
