Final answer:
The correct answer is option B) 20-40.
Step-by-step explanation:
In Erikson's psychosocial theory, the stage associated with young adulthood typically encompasses the age range from 20-40 years old. This developmental period focuses on the psychosocial challenge of intimacy versus isolation. During these years, individuals are expected to explore personal relationships, nurture close bonds, and form long-term commitments.
In contrast to adolescence, which is marked by exploration and sometimes conflict over day-to-day issues like curfews and homework, young adulthood is a time for forming a deeper sense of self and connecting with others.
As individuals enter into young adulthood, they usually complete their formal education, embark on careers, and often start families. The significance of this stage is highlighted by Erikson's belief in the importance of establishing a strong sense of self during adolescence as a precursor to forming successful intimate relationships in early adulthood. Hence, the correct answer to the student's question is B) 20-40.
