Which method of fs module is used to delete a file?(1 Point)fs.delete(fd, len, callback)fs.remove(fd, len, callback)fs.unlink(path, callback)None of the above.

The method used in the fs module to delete a file is fs.unlink(path, callback).

Explanation:

In Node.js, the fs (file system) module provides various methods for interacting with the file system. One of these methods, fs.unlink(), is specifically designed to delete files. When you call fs.unlink(path, callback), you provide the path of the file you want to delete as the first argument. The second argument is a callback function that will be executed after the deletion is attempted, allowing you to handle any errors or confirm the successful deletion of the file.

The other options provided, such as fs.delete(fd, len, callback) and fs.remove(fd, len, callback), do not exist in the Node.js fs module, which makes them incorrect. Therefore, the correct answer is fs.unlink(path, callback), as it is the designated method for deleting a file in the file system managed by Node.js.

Final Answer:

fs.unlink(path, callback)
