A business becomes a separate legal entity after it has

When a business is incorporated, it becomes a separate legal entity, meaning it is treated as a separate entity apart from its owners. This means that the business can enter into contracts, sue or be sued, own property, and conduct other legal activities in its own name. The incorporation process involves registering the business with the appropriate government authority, which creates a new legal entity separate from the owners of the business. Therefore, the correct option is "been incorporated".
