Which types of listing agreements specify that the broker will not be compensated unless they directly facilitate the sale?

An exclusive right to sell listing and a net listing are not forms of agreements that specify the broker will not be compensated unless they directly facilitate the sale. An exclusive right to sell listing guarantees the broker a commission regardless of who facilitates the sale, while a net listing has a predetermined minimum amount the seller will receive and anything above that amount will go to the broker. Multiple listing service is not a type of listing agreement and does not address broker compensation. Therefore, the most appropriate choice is B, which includes both open listing and exclusive agency listing.
