A 12-year-old boy takes great pride in the science project he completed for the regional fair. Even though he didn't win, he feels that he did a great job. Which of Erikson's psychosocial stages has this child mastered?

Choice A reason: Initiative vs. Guilt occurs in preschool-aged children and involves developing the ability to take initiative, not mastery of accomplishments in school tasks. Choice B reason: Autonomy vs. Shame and Doubt occurs in toddlers and involves independence and self-control, not school-age achievements. Choice C reason: Industry vs. Inferiority occurs in school-aged children (6–12 years) and involves developing competence, confidence, and pride in accomplishments, which aligns with this boy’s response. Choice D reason: Identity vs. Role Confusion occurs in adolescence and relates to self-identity development rather than competence in school tasks.
