Final answer:
The correct answer is b) Yes, unless the commission rate is less than 6%.
Step-by-step explanation:
The correct answer is b) Yes, unless the commission rate is less than 6%.
According to the question, Broker Bob has a contractual referral fee relationship with Big Insurance Company. This means that if any agent listed a property, a referral fee is required to be paid. However, there is an exception if the commission rate is less than 6%. In that case, the fee does not need to be paid.
Therefore, both the agent and Broker Bob will be required to pay the referral fee unless the commission rate is less than 6%.
