Step-by-step explanation:
The self-concepts during social interaction primarily try to fulfill the needs for competence and mastery and, to a certain extent, approval and belonging. According to Erikson's theory of psychosocial development, the main task of the adolescent is feeling competent.
Formation of a positive self-concept begins in toddlerhood, establishing autonomy and confidence in one's abilities. In adolescence, this self-concept is re-evaluated as teens form an identity, internalizing messages about their strengths and weaknesses.
Those who reach a sense of identity are better positioned to contribute positively to society by mastering the developmental tasks set in each life stage, ultimately leading to a sense of competence. The correct options are a,c.
