Answer
Sealed classes enforce strict hierarchy control.
Sealed classes offer a way to manage and enforce a controlled class hierarchy, preventing rogue implementations. This is especially relevant in complex systems like e-commerce, where it's crucial to maintain strict control over entities like orders or payments. By using sealed classes, you guarantee that only authorized subclasses participate in critical business logic, enhancing security and maintainability.
