Which of the following best describes a correct implementation of the Command design pattern in an application where you need to perform various file operations like open, save, and close?

Create a single class that includes methods like open$(),$ save$(),$ and close$(),$ and call these methods directly from the client code.

Define a FileOperation interface with a method execute$().$ Implement this interface in different classes like OpenFileCommand, SaveFileCommand, and CloseFileCommand that encapsulate the corresponding file operation.

Use multiple interfaces for different file operations and implement these interfaces in a single class that handles all file operations.

Encapsulate all file operations in a global static class with static methods for open, save, and close, allowing these methods to be called from anywhere in the application.
