Though His Original Theory of Personality Has Been and Continues

Though his original theory of personality has been and continues to be criticized, Freud's ideas served to inspire the work of other personality theorists who have made significant contributions to the field. In this sense, Freud's theory could be considered "useful" because it:

A) suggested that personality is shaped by behaviours that appear to fit together.
B) provided a comprehensive framework to explain known facts.
C) allowed researchers to predict future events with relative accuracy.
D) stimulated the discovery of new knowledge.
