Which agreement gives an agent an exclusive right to work with a seller but allows the seller to sell the property themselves?

The correct answer is C, the exclusive agency listing. This type of agreement provides the agent with the exclusive right to represent the seller in the sale of the property; however, it concurrently allows the seller to retain the right to sell the property independently without owing any commission to the agent if they succeed in finding a buyer on their own.

In this arrangement, the agent's role is emphasized, as they get the benefit of exclusive representation, which can lead to targeted marketing efforts. However, the seller retains a greater degree of control over the sale process by having the option to conduct their own sales activities.

Other agreements, such as exclusive right to sell agreements and exclusive listing agreements, typically do not permit the seller to sell the property independently without incurring a commission obligation to the agent. The dual agency agreement refers to a scenario where an agent represents both the buyer and the seller in the same transaction, which does not pertain to exclusive rights in the way described in the question.
