How many partners are involved in a partnership?

A partnership is a business structure where two or more individuals come together to operate a business and share its profits and liabilities. The essential characteristic of a partnership is the involvement of multiple partners who collaborate in managing and running the business. This can range from as few as two partners to many more, depending on the specific type of partnership and the regulations under which it operates.

Options such as one partner do not align with the definition of a partnership, as a singular individual would typically establish a sole proprietorship instead. The choice that includes five or more partners is too restrictive, as partnerships can legally include just two partners. Lastly, the option of having none does not apply because, by definition, a partnership requires at least two individuals working together.

Thus, the correct answer accurately reflects the fundamental requirement of a partnership: it must involve two or more partners.
