d. pablo picasso

The answer is B: Freud.

Sigmund Freud was an Austrian medic and neurologist and the inventor of psychoanalysis (a form of psychology). In his theoretical works, most notably in the Interpretation of dreams, he popularized the idea of the subconscious as an element of the mind that, although it could never be made fully conscious, it could be expressed by interpreting both the latent and manifest contents of dreams. Later on he would add that bodily symptoms could also be a gateway to the subconscious.

When evaluating an author's style, the reader has to make sure that he remains as neutral as possible before the evaluation.

Finally, an evaluation should be more than a simple summary of the text. It requires a judgement on the methods that the author uses in order to convey a message. This judgement needs to be performed in a careful and thoughtful way.
