The correct answer is A. Solidified a sense of identity
Explanation:
According to the psychoanalysts Erik Erikson, one of the stages in psychosocial development is role confusion or identity vs. role confusion. This stage occurs during adolesce and involves teenagers exploring values, preferences, etc. to define their identity. For Erikson, this occurs because teens do not have a defined sense of identity and need to go through the role confusion stage to develop it. Also, this is part of the transition between childhood and adulthood. Thus, for Erikson teens who suffer role confusion have not yet solidified a sense of identity.
