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

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.
