How is a file closed in the BasicFileOutput example?

Using the close method
Automatically when finished
Using the flush method
By garbage collection

The correct answer is: Using the close method

In the BasicFileOutput example, a file is closed by explicitly calling the close method. The other options are incorrect because - B: The file will not automatically close when finished, as it needs to be manually closed to avoid potential memory leaks. - C: The flush method is used to ensure all buffered data is written to the file, but it does not close the file. - D: Garbage collection only occurs when there are no more references to an object, so relying on it to close a file is not reliable.
