Final answer:
In Erikson's theory of psychosocial development, late adulthood is marked by the crisis of integrity versus despair, where individuals reflect on their life's worth and achievements, leading to feelings of fulfillment or regret.
Step-by-step explanation:
The late adulthood stage as defined by Erik Erikson is characterized by the psycho-social crisis of integrity versus despair. Individuals in this stage reflect on their lives and feel either a sense of satisfaction or a sense of failure. Those who are successful at this stage often feel a sense of integrity and can look back on their achievements with few regrets. On the other hand, those who are unsuccessful may experience feelings of despair, reflecting on missed opportunities and perceiving their lives as wasted. These individuals may struggle with feelings of bitterness and depression.
To address the student's specific question, the late adulthood stage is best characterized by option D: Person evaluates whether life has been worthwhile, indicating a process of self-reflection on life's accomplishments and failures and the subsequent feelings of integrity or despair.
