Is D correct because, while the author stated Ellison received criticism that "his indulging in European fictional modes lessened his contribution to the development of a distinctly African Novelistic Style," the author only directly responded to the criticism regarding art and political action? If the author had addressed more explicitly the criticism regarding "European fictional modes," would D still be correct?
I did not really like any of the other answers either, but I ended up rejecting D and choosing E because I thought D did not wholly encapsulate the purpose of the passage.
