Which of the following listings would allow more than one brokerage firm to work simultaneously to sell the owner's property and claim the full commission?

An exclusive listing grants a single brokerage firm the exclusive right to sell the property, meaning that no other broker can claim a commission, even if they find a buyer. This type of agreement limits the brokerage's competition and creates a more controlled selling environment for the property owner.

A written listing is a general term that does not specify the nature of the agreement. It may refer to exclusive or open listings and does not inherently allow multiple brokers to work simultaneously. Thus, it lacks the specific characteristics of an open listing that facilitate competition among different brokerage firms.

An exclusive right-to-sell listing provides one brokerage firm with exclusive rights to sell the property and guarantees that they receive a commission regardless of who sells the property. This agreement also restricts multiple brokers from working on the same property, unlike an open listing.
