What arrangement offers consumers a bundle of services?

The choice of a Controlled Business Arrangement stands out as it specifically pertains to a legal arrangement where multiple services are offered to consumers by affiliated businesses, typically in the real estate industry. This setup allows real estate professionals to provide a seamless experience by combining various services, such as real estate sales, mortgage lending, and title insurance, under one umbrella.

In a Controlled Business Arrangement, consumers benefit from the convenience of accessing a suite of services that may reduce their overall transaction costs and streamline processes. This kind of arrangement is often designed to ensure compliance with regulations while offering consumers a comprehensive package that addresses multiple needs in one transaction.

The other choices represent different types of agreements which do not inherently bundle services for consumers in the same way. A Service Contract usually involves specific obligations between a service provider and a consumer rather than a bundled offering. A Partnership Agreement is focused on the collaboration between partners in running a business without necessarily providing a variety of consumer services. Similarly, a Franchise Agreement relates to the operation of a franchise business model which may include certain services but doesn't directly highlight the bundled offering aspect. Hence, Controlled Business Arrangement is the most appropriate choice reflecting the context of bundling services for consumer benefit.
