Final answer:
A Limited Liability Partnership (LLP) is considered a hybrid organizational form because it blends elements of partnerships' operational flexibility with the limited liability features of a corporation.
Step-by-step explanation:
The question asks which of the listed options is considered a hybrid organizational form. Among the options given, the Limited Liability Partnership (LLP) is considered a hybrid organizational form. This is because it combines elements of both partnerships and corporations. An LLP provides the limited liability features of a corporation with the tax efficiencies and operational flexibility of a partnership.
In contrast, a sole proprietorship is owned and run by one individual, where there is no distinction between the owner and the business entity, leading to unlimited personal liability. A partnership is a business owned by two or more people who share profits and responsibilities, and it also involves shared liability. A corporation is a legal entity separate from its owners, providing limited liability but subjected to corporate taxes and regulations.
