According to Erik Erikson's theory of psychosocial development, which specific psychosocial strength or virtue develops as a result of the successful resolution of the crisis 'Identity vs. Role Confusion' during adolescence?

In Erik Erikson's theory of psychosocial development, the fifth stage relates to 'Adolescence' (approximately 12 to 18 years), where the core crisis is 'Identity vs. Role Confusion'. Successful resolution of this crisis develops the virtue known as 'Fidelity', which reflects the ability to commit to others and sustain one's value system. Option (a) 'Purpose' is associated with early childhood (Initiative vs. Guilt), option (c) 'Competence' is associated with middle childhood (Industry vs. Inferiority), and option (d) 'Care' is associated with adulthood (Generativity vs. Stagnation).
