Final answer:
An exclusive right-to-purchase agreement creates an exclusive agency relationship between a buyer and a broker. This form of agreement requires the buyer to work exclusively with one broker, contrasting with other types of agreements that do not require exclusivity or apply to different parties.
Step-by-step explanation:
The question asks which form creates an exclusive agency relationship between a buyer and a broker. The correct answer is A) Exclusive right to purchase agreement. An exclusive right-to-purchase agreement is a contract where a buyer agrees to work exclusively with one broker when looking for and negotiating the purchase of property. The broker, in return, dedicates effort to finding properties that match the buyer's criteria and represents the buyer's interests. This contrasts with an open buyer agency agreement (B), which does not require exclusivity, a net listing agreement (C), which involves a different context where a broker is selling property for the owner, and an exclusive right to sell agreement (D), which is an exclusive contract between a seller and a listing broker, not a buyer and a broker.
An exclusive dealing agreement can have different implications depending on its use. In the context of manufacturer-retailer relationships, it is designed to encourage competition among dealers when manufacturers provide products exclusively to certain dealers, such as Ford providing cars solely to Ford dealers. However, the exclusive nature can sometimes limit competition by restricting who can sell a manufacturer's products, potentially having an anticompetitive effect on the market.
