Step 1: Understanding the Question:
The question asks us to identify the theoretical concepts proposed specifically by the psychoanalyst Carl Gustav Jung, the founder of Analytical Psychology.
Step 2: Key Formula or Approach:
To determine the correct answer, we must isolate Carl Jung's unique contributions from those of Sigmund Freud and Karen Horney.
Step 3: Detailed Explanation:
• Let us analyze each of the five concepts:
• A. Ego defenses: Although Carl Jung discussed the ego, ego defense mechanisms were formally proposed and detailed by Sigmund Freud and further expanded by Anna Freud.
• B. Psychic determinism: This is a fundamental assumption of classical Freudian psychoanalysis stating that all mental processes have an underlying cause.
• C. Collective unconscious: This is Carl Jung's unique conceptualization of a deep layer of the unconscious mind containing archetypes shared among all human beings.
• D. Principle of opposites: Carl Jung introduced this principle to explain the flow of psychic energy (libido), stating that every physical and mental state contains its own opposite.
• E. Neurotic needs: The concept of ten neurotic needs was proposed by neo-Freudian psychoanalyst Karen Horney, not Carl Jung.
• Consequently, only C (Collective unconscious) and D (Principle of opposites) are propositions formulated by Carl Jung.
Step 4: Final Answer:
The correct option is C & amp; D Only, which corresponds to Option (C).
