An authorization to sell between a broker and a seller is considered a contract for personal service because this agreement is fundamentally about the relationship and the services the broker will provide to sell the property on behalf of the seller. In real estate, the broker acts as an agent for the seller, representing their interests in the transaction. This type of contract is based on a personal relationship, where the seller entrusts the broker with the task of selling their property, and it typically includes specifics about the commission and the responsibilities of the broker.

The other options do not capture the essence of this relationship or the nature of the agreement. A contract of sale and an agreement of sale are more focused on the actual transaction of buying and selling the property, while a purchase contract usually involves the terms between a buyer and a seller regarding the transfer of title. These options do not accurately reflect the service-oriented nature of the authorization between the broker and the seller. The emphasis in a contract for personal services is on the facilitation of a service, which is precisely what the broker provides.
