Answer:
Oral warranty was used by the seller.
Explanation:
The scenario shows that the proper warranty made by the seller to win N’s interest was premised on need. That is to say, by demonstration, N walks into the departmental store and was immediately approached by the seller who begins by exchanging pleasantries and thereafter introduces the new product to N by specifically outlining its benefits as compared to previous models. All of this warranty was made orally and not written.
