Answer 1

Correct answer is (c) __destruct()

To explain: You can use this method to perform any final cleaning up that might be necessary. Imagine, for example, a class that saves itself to a database when so ordered. I could use the __destruct() method to ensure that an instance saves its data when it is deleted.
