On many Find the Assumption questions, a trap answer won't actually address the conclusion. Because the question specifically asks you to find an assumption necessary to draw that conclusion, an answer that has No Tie to the Conclusion must be wrong. Answer (A) in the problem above is a good example. The conclusion does not depend upon whether different people would agree to classify the same item as a luxury good. Rather, the conclusion is about what causes someone to spend less money on anything that that individual believes to be a luxury good.
