What is the relationship between Sofia and Luciana, the buyer's representative?

In real estate transactions, the distinction between a client and a customer is critical in understanding agency relationships. In this scenario, if Sofia is being represented by Luciana, it is established that Sofia is the client of Luciana, given that she is receiving personalized service and advice in the context of purchasing a property. A client typically has an established contractual relationship with the agent, which is rooted in fiduciary obligations, whereas a customer does not have such a relationship.

When we examine the choice stating that Sofia is Luciana's customer, it indicates a lack of formal relationship where Luciana owes no fiduciary duties to Sofia. A customer relationship generally implies a more limited engagement, where some information might be provided, but it does not include the comprehensive support and loyalty of a client relationship.

This makes the selection of Sofia as Luciana's customer reflective of a situation where the agency duties, such as loyalty, disclosure, and obedience, that would be inherent in a typical client-agent relationship, are not present or acknowledged.
