Final answer:
The answer that would prevent ABC Relocation Company from receiving the requested fee is option b) Louisa has an exclusive buyer agency agreement with the buyers.
Step-by-step explanation:
In this scenario, the answer that would prevent ABC Relocation Company from receiving the requested fee is option b) Louisa has an exclusive buyer agency agreement with the buyers. An exclusive buyer agency agreement means that Louisa is the exclusive agent representing the buyers in their home search. The referral fee would not apply in this case because the buyers were already working with Louisa and did not use ABC Relocation Company as their agent.
Options a), c), and d) are not relevant to this situation. Being licensed in another state or not having a written relocation agreement does not necessarily impact the referral fee. Additionally, the buyer's request to not be paid does not prevent ABC Relocation Company from receiving the fee.
