I agree with Kristeen. But what's the deal with option C? How could the old and new classifiers being identical cause an error? That seems a bit strange to me.
Hmm, I think options B and D are the correct answers. Trying to reclassify an object with an abstract class or without providing any new classifiers seems like it would definitely cause errors.
