C) Sigmund Freud

Explanation:

Sigmund Freud found that the psychological forces developing people's performance are largely unaware as well as that a personality cannot fully realize his or her personal motivations. Basically psychological forces are a collection of emotions, ideas, as well as behavioral improvements driving to development. And as we should know that "Sigmund Freud" was a man who born in Austria and was a neurologist and the originator of psycho-analysis. That is a clinical approach for operating psychopathology through conversational dialogues.
