Step-by-step explanation:
The question posed revolves around the understanding of unconscious conflicts and their manifestation in anxiety disorders. The correct answer to this question is a) Sigmund Freud, who is the theorist acclaimed for his work on psychoanalytic theory, which holds that most of our thoughts and feelings are buried in the unconscious mind. According to Freud, the unconscious mind is a repository of repressed memories and desires, which are shielded from our conscious awareness. These can manifest in various ways, including dreams, slips of the tongue, and psychological symptoms such as anxiety disorders. Freud strongly believed that unconscious conflicts, which arise from the struggle to reconcile our innate desires with societal rules, cause inner conflict and can result in mental health issues including anxiety disorders. His psychoanalytic approach focused on accessing the unconscious mind through techniques like dream analysis, free association, and the examination of verbal slips to address these buried conflicts.
