Correct Answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

Correct Answer: D

Rationale: Castration anxiety is a concept specific to the Phallic stage in psychoanalytic theory, according to Sigmund Freud. During the Phallic stage, children experience the Oedipus complex (boys) and Electra complex (girls), where they develop unconscious desires for the opposite-sex parent and fear castration by the same-sex parent. This anxiety is a crucial aspect of the Phallic stage, making it the correct answer. The other stages (Genital, Oral, and Anal) do not directly involve castration anxiety and focus on different aspects of psychosexual development.

Correct Answer: C

Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5 is the phallic stage. During this stage, children focus on the genitals and start to identify with the same-sex parent while developing the superego. Choice A, the oral stage, occurs during infancy (0-1 year), where gratification is centered around the mouth. Choice B, the anal stage, occurs between the ages of 1 and 3, focusing on toilet training. Choice D, the genital stage, is the final stage in Freud's theory, occurring from puberty onwards, where the focus is on mature sexual relationships.
