Haha, this question is a real head-scratcher! I'm gonna go with option B just for the heck of it. Maybe the exam folks are trying to trip us up with this one.

I'll go with option D, just to mix things up.

Ah, the old exception handling conundrum. I reckon option B is the way to go. Gotta love those pesky checked exceptions, am I right?

I'm not sure about this one. The question seems a bit tricky, but I'm leaning towards option C. Replacing line n2 with 'void ride() throws Exception {' might do the trick.

Hmm, I think the correct answer is B. Replacing line n1 with 'protected void ride() throws Exception {' would allow the code to print 'Happy Journey!' since the overriding method in the subclass must have the same or a broader exception declaration as the superclass method.

Yes, changing line n1 to 'protected void ride() throws Exception {' is the way to go.

But if we replace line n2 with void ride() throws Exception, it won't throw FuelNotAvailException.
