This is a challenge im facing too. I second-guess and question myself on questions that aren't tricky, while finally having the skills to overcome more challenging questions. I had to get back to trusting my gut and getting through the first 10 questions by identifying the right answer without even reading the rest of the answers.

Wait, how can you throw out the rule that "not just for its value as an investment" when they clearly make reference to that in (B), "not sure that the vase will appreciate much in value." All this because you can conflate "desirable for its intrinsic qualities" with "value as an investment." I know its not the right answer either way but this is junk advice is it not?
