Final answer:
When a real estate agent transfers brokerages, they are typically required to notify their clients and may continue with existing engagements only if specifically authorized by their former broker.
Step-by-step explanation:
The question pertains to the responsibilities and actions a transferring licensee must take when changing brokerage affiliations. Generally, when a real estate agent (licensee) transfers from one broker to another, they are typically required to notify their existing clients about the change in their brokerage affiliation. This is to ensure transparency and maintain trust with the clients. Depending on the agreement between the transferring licensee and the previous broker, option C may be true; the licensee may continue with written brokerage engagements if specifically authorized by the existing broker. It is essential to refer to state regulations and contractual agreements to determine the appropriate course of action in such situations. Options A and D might not generally be accurate without specific contractual permission from the previous broker.
