Final answer:
The agent should inform the seller that it would be illegal to accept the listing under the condition of selling to only Caucasians and promote equal opportunities for all potential buyers.
Step-by-step explanation:
According to the law, discrimination based on race is illegal in housing. Therefore, the agent should inform the seller that it would be illegal to accept the listing under the condition of selling to only Caucasians.
It is important to emphasize that racial discrimination is against the law and goes against principles of fairness and equality. By informing the seller of the legal requirements, the agent is promoting equal opportunities for all potential buyers.
Instead of restricting the listing to Caucasians, the agent should advertise the home to a diverse range of potential buyers, ensuring that all interested parties have an equal opportunity to purchase the property.
