Answer 2 would restrict inner classes to extending only the Object class, Answer 3, on the other hand, includes the Object class in its 'any class or interface' statement.

Mn~~~ Ray, I think the question is "MUST extend", NOT "could extend" . An inner class could extend any classes and interfaces of course.
