Final answer:
Erikson regarded the establishment of intimacy during the young adulthood stage, termed 'Intimacy vs. Isolation', as the positive outcome to be achieved after having developed a sense of self in adolescence. Hence, option (b) is correct.
Step-by-step explanation:
The positive outcome Ivan Erikson considered to be crucial during the young adulthood stage is the development of intimacy as opposed to isolation. This is represented as Intimacy vs. Isolation. Erikson suggested that forming intimate relationships with others is essential after developing a sense of self in adolescence, typically taking place during one's 20s through early 40s. Those who succeed in establishing strong relationships foster a sense of companionship and connection, whereas those who fail may feel isolated and alone.
During the "Intimacy vs. Isolation" stage, which typically occurs in young adulthood, individuals seek to establish close, meaningful relationships with others. Successfully resolving this conflict involves forming intimate connections and developing a sense of commitment and shared identity with a romantic partner or close friends. Those who navigate this stage successfully are more likely to experience fulfilling relationships, while individuals who struggle with this stage may face feelings of isolation or a lack of meaningful connections.
