Correct Answer: A

Rationale: The correct answer is A: 'Industry vs. inferiority.' According to Erikson's theory, school-age children (approximately 6-12 years old) are in the stage of industry vs. inferiority. In this stage, children focus on developing a sense of competence and productivity. Choice B, 'Autonomy vs. shame and doubt,' is incorrect as it refers to the stage that occurs during early childhood (1-3 years old). Choice C, 'Identity vs. role diffusion,' pertains to adolescence (12-18 years old). Choice D, 'Trust vs. mistrust,' is related to the stage of infancy (0-1 year old). Therefore, option A is the most appropriate stage for school-age children in Erikson's theory.
