I got this question correct,but i think "her" ( the release of her controversial) doesn't have a proper antecedent.Obviously all the answer had "her" so that helped in cracking the right answer. Was this done on purpose-to show that we have to choose the most appropriate answer or can we learn some new rule from this question?
