A broker who prepares a purchase agreement MUST give a copy of this signed document to the buyer?

The correct choice indicates that a broker is required to provide a signed copy of the purchase agreement to the buyer as soon as practically possible. This reflects the principle that transparency and documentation are crucial in real estate transactions. Ensuring that the buyer receives a copy promptly allows them to reference the agreement, understand their obligations, and remain informed throughout the transaction process.

Offering this copy at the earliest feasible moment helps establish trust and facilitates clear communication between the broker and the buyer. Additionally, it ensures that both parties have the same understanding of the terms and conditions outlined in the agreement, which is critical for a smooth transaction.

Other options suggest various timeframes for when the signed document should be delivered, but do not emphasize the importance of promptness in a practical sense as the correct choice does. For example, specifying a fixed time period or a point in the transaction such as closing does not align with the real-world need for timely access to the contract by the buyer.
