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.

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.

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