The correct answer is A. Massachusetts clearly distinguishes the authority of a broker from that of a salesperson.

The Board ' s consumer guidance states that a salesperson must be affiliated with a broker and work under that broker ' s supervision. The salesperson cannot independently operate a real-estate business and has no authority or control over brokerage escrow funds.

Massachusetts licensing curriculum likewise states that a salesperson cannot be self-employed, may affiliate with only one broker at a time, cannot receive valuable consideration from anyone other than the broker, and may not complete the transaction independently.

A salesperson can perform substantial transaction activities—showing property, working with buyers and sellers, advertising listings, and participating in negotiation—but those activities occur within the responsible broker ' s brokerage structure.

This broker-supervision requirement is one of the most important Massachusetts-specific distinctions tested on the state portion of the examination.
