What type of listing offers the broker the most protection?

A listing agreement that offers the broker the most protection is the exclusive right-to-sell listing. This type of agreement guarantees that the broker receives a commission regardless of who sells the property, whether it's the broker, the owner, or another agent. It provides the broker with greater incentive to market the property aggressively and ensures they are compensated for their efforts in securing a sale. Additionally, it establishes clear terms and conditions, minimizing potential disputes.
