Answer:
An express warranty
Explanation:
Express warranties can be made in writing, orally or even inferred by the salesperson's conduct. Even if the salesperson made a mistake by offering an express warranty, it is still valid. An express warranty states that a good or service will specifically be a certain way, or perform in a certain way. When a salesperson shows a model of the good, that is considered a express warranty that the good will be the same as the model.
