Option B
German-American psychologist Erik Erikson and his collaborator and wife, Joan Erikson, based on case study imagined eight stages of psycho-social development that they theorized good individuals pass through as they develop from infancy to adulthood.At each stage, the person must decide a challenge or an existential dilemma.
Case study helps in deriving some theory of development. These studies gives many conclusions to be drawn from the problems. The impact of social activity was described in Erikson's theory in whole lifespan. The actions and behaviors are motivated by competence sense.
