Which of the following would be an appropriate name for a class that holds invoice details?

The most appropriate name for a class that holds invoice details is "Invoice." Naming conventions in programming and object-oriented design typically suggest that class names should clearly and accurately reflect the purpose and content of the class.

In this case, the "Invoice" class specifically denotes that it contains all necessary details related to invoices, such as invoice number, date, customer information, items sold, and total amount due. Using a precise name like "Invoice" improves code readability and maintainability, making it easier for developers to understand the structure and purpose of the class at a glance.

This choice eliminates ambiguity, ensuring that anyone working with the code can immediately recognize that this class deals specifically with invoices, as opposed to other financial documents. Using "Transaction," "Receipt," or "Bill" could introduce confusion, as these terms may encompass different types of financial interactions or documents that do not specifically refer to an invoice. Each of these terms implies different contexts or details that are not encapsulated within a standard invoice.
