9) A
A is basically paraphrasing the sentence given in the question. We now have more money and more misery. This means that even though we are getting richer, we are not getting any happier.
Even though B should be hypothetically correct, the evidence shows that it is in fact wrong.
C and D are irrelevant as these two statements are neither suggested by the text nor can they be inferred from the text.
