Final answer:
The statement is false; a corporation needs to incorporate only once in a state and then register as a foreign corporation in other states where it conducts significant business.
Step-by-step explanation:
The statement that a corporation must be incorporated in each state that it does business in is false. A corporation is a legal entity that is created under the laws of a single state, known as the state of incorporation. Once a corporation is formed, it does not need to incorporate in every state where it conducts business. However, it typically must register as a foreign corporation in other states where it has significant operations, which is a different process from incorporation. This registration usually involves paying fees and taxes, and it allows the corporation to legally do business in those states. But the actual incorporation only occurs once, in a specific state that the business chooses, often based on favorable tax laws, regulatory environment, or other business considerations.
