    The class correctly implements the Runnable interface with a legal public void run() method. Option A is incorrect because interfaces are not extended; they are implemented. Option B is incorrect because even though the class would compile and it has a valid public void run() method, it does not implement the Runnable interface, so the compiler would complain when creating a Thread with an instance of it. Option D is incorrect because the run() method must be public.
