Which of these is a type of partnership in business?

The type of partnership in business is called a "limited partnership". A limited partnership is a type of partnership where there are two types of partners: general partners and limited partners. The general partners are responsible for managing the business and are personally liable for the business's debts and obligations. The limited partners, on the other hand, are passive investors who contribute capital to the business but do not take part in its management. They are not personally liable for the business's debts and obligations beyond the amount of their investment. This type of partnership is often used when one or more investors want to invest in a business but do not want to take an active role in its management. The limited partnership structure allows them to do so while also limiting their personal liability for the business's debts and obligations.
