Which of the following psychological statements is most authentic and scientifically valid regarding the structural system of personality—(1) Id, (2) Ego, and (3) Superego—propounded under Sigmund Freud's 'Psychoanalytic Theory', and the defense mechanisms operated by them such as 'Rationalization', 'Repression', and 'Sublimation', along with their real psychological implications for students' stress management, moral development, and emotional adjustment in classroom teaching?

According to Sigmund Freud's psychoanalytic theory, personality consists of three main components: Id, Ego, and Superego. The Id operates on the pleasure principle and seeks immediate gratification. The Ego operates on the reality principle, balancing the Id and the Superego. The Superego represents morality, ideals, and social values, controlling the immoral tendencies of the Id. Option 'b' accurately describes the scientific nature of this theory. Options 'a' and 'c' are incorrect because the Id operates on the pleasure principle, not the reality principle, and the Ego manages reality. Option 'd' is incorrect because sublimation is a positive and mature defense mechanism where antisocial energy is channeled into socially acceptable creative activities rather than merely repressed.
