Final answer:
The business structure being described is a partnership, which is formed when two or more individuals, in this case the brothers, share ownership and managerial responsibilities of their respective stores.
Step-by-step explanation:
The type of business structure described in the scenario is a partnership. Initially, the business ('Help me now') was likely operating as a sole proprietorship since it was owned and run by just one person, the owner. However, as the owner is considering opening another store operated by his brother, and both will be responsible for managing their respective stores, this indicates the formation of a partnership. A partnership involves two or more individuals who share the responsibility, profits, and liabilities of the business. The type of business structure being described in the question is Partnership (A).
A partnership is a form of business organization in which two or more individuals share the ownership and management of a business. In this case, the owner of "Help me now" and his brother will be responsible for managing the stores in Pittsburgh and Baltimore respectively.
