Which of the following attributes is most appropriate for the parent class LibraryItem?

Imagine you're developing a software system for a library. In this system, you need to manage different types of items that can be borrowed, such as books, magazines, and DVDs. Each of these items shares some common characteristics, like a title and a unique identifier, but they also have specific attributes. For instance, a book has an author, a magazine has an issue number, and a DVD has a duration. By using inheritance, you can create a general class for all items and then more specific classes for each type of item.
