Answer and Explanation:
Carl Jung, a Swiss psychiatrist and psychoanalyst, had a complex relationship with his mentor Sigmund Freud, and his views and theories diverged from those of Freud. Therefore, option A, "refused to disagree with Sigmund Freud out of loyalty to his mentor," is not an accurate statement.
Option B, "argued against his mentor Sigmund Freud's theories," is the correct answer. Jung initially admired Freud and collaborated with him, but over time, he developed his own psychological theories that differed significantly from Freud's psychoanalytic approach. Jung disagreed with Freud on various fundamental concepts, such as the role of the unconscious, the nature of dreams, and the importance of sexuality in human psychology.
Option C, "chose a very different occupation from his mentor Sigmund Freud," is not accurate. Both Jung and Freud were psychologists and psychoanalysts, although they had different perspectives and approaches within the field.
Option D, "never became a famous psychologist like his mentor Sigmund Freud," is also not accurate. Carl Jung became a renowned and influential figure in the field of psychology, known for his theories on analytical psychology, the collective unconscious, archetypes, and individuation. He made significant contributions to the development of psychological thought and is considered one of the most important psychologists in history.
