Which term is the energy of all life instincts including sexual energy?

• A. Libido
• B. Id
• C. Narcissistic personality disorder
• D. Interpretation

Answer: (A)

In Freudian theory, the energy behind life instincts is called libido. This psychic energy powers drives tied to survival, growth, and sexual motivation, and it can be expressed in many forms beyond just sexual activity—creative work, relationships, and personal development all draw on this energy. Libido is the force that fuels these life-affirming impulses, making it the best fit for the idea of the energy of all life instincts including sexual energy.

The other terms aren’t about energy itself. The id is a structural part of the psyche that houses instinctual drives, but it’s not the energy itself. Narcissistic personality disorder is a clinical diagnosis describing a pattern of grandiosity and need for admiration, not a type of energy. Interpretation is a psychoanalytic technique used to uncover unconscious meanings, not a term for energy.
