B, a real-estate listing agreement, is correct. Massachusetts Board contract curriculum specifically provides that listing contracts may be written or oral, although sound professional practice strongly favors written agreements.

The Massachusetts Statute of Frauds generally requires a sufficient signed writing for contracts for the purchase or sale of real property to be enforceable against the party to be charged. Agreements that cannot be performed within one year also generally fall within the Statute of Frauds, which makes a twenty-year oral lease an inappropriate answer.

An oral listing agreement should not be confused with an oral contract transferring ownership of real estate. A listing agreement is fundamentally an employment relationship between broker and client rather than the conveyance itself.

Written listings are preferable because they establish price, duration, scope of authority, brokerage relationship, compensation, and termination provisions and significantly reduce evidentiary disputes.
