Final answer:
When a broker loses his license, the salespeople working under him should activate their licenses with other brokers to remain compliant with real estate regulations.
Step-by-step explanation:
When a broker loses his license, his salespeople should not continue to operate as before. According to real estate laws, a salesperson must be under the supervision of a licensed broker to complete transactions. Therefore, the correct option would be for the salespeople to activate their licenses with other brokers. This means they should seek employment under another licensed broker to remain in compliance with real estate regulations. Continuing to operate without a licensed broker, attempting to close transactions swiftly, or waiting for the reinstatement of the broker's license are not proper courses of action according to the ethical and legal standards in real estate.
