Answer:
A. Selfishness and greed
Explanation:
With these words, said by one of the characters of the novel, Nick, who was referring to Tom and Daisy, Fitzgerald is criticizing the ruthless, selfish and greedy nature of these two characters: they do as they please, have no consideration for others, do harm on purpose, and simply walk away from the mess they make and go back to their materialistic way of living. Their behavior, indeed, was intended to reflect the American way of living during the 1920s which was characterized for little regard for morals.
