Answer:
B) Sue has apparent authority to make warranties such as the one that she made. Therefore, the store is bound.
Explanation:
Apparent authority refers to a situation where a third party (in this case Pat, the customer) can reasonable assume that an agent (Sue, the salesperson) has been given authority to decide or act in favor a of principal (Ivey's Fashion Store). Since Sue works for Ivey's, it was reasonable for Pat to believe that Sue had the authority to make express warranties.
