What are the characteristics of later adolescence and young adulthood (17–26 years)?

You’re welcome.

Thank you for the detailed explanation.

Orientation is towards defining one’s functional role in terms of ongoing education, work, lifestyle, and relationship plans. There is a degree of psychological autonomy, a realistic body image, and a more comfortable sense of one’s sexual identity. Relationships increasingly demonstrate mutual caring and responsibility. Illness may result in reduced vocational options, and an increasing dependence with a growing sense of inadequacy, often expressed through anger and non-compliance. Concerns about relationships in the present and future and potential for child-bearing may predominate.
