Which of the following is not one of the four types of business organization structures?

A franchise is fundamentally different from the traditional types of business organization structures like sole proprietorships, partnerships, and corporations. The first three represent ownership structures, where the business is owned and operated under specific legal frameworks.

A sole proprietorship is a business owned by a single individual, who holds full liability and control. Partnerships involve two or more individuals sharing ownership and responsibilities, while corporations are separate legal entities owned by shareholders.

In contrast, a franchise is a business model that allows individuals or groups (franchisees) to operate a business using the name, branding, and operational model of an established company (the franchisor). It is more of a licensing agreement rather than an ownership structure on its own. This distinction sets franchises apart from the primary categories of business organization.
