According to Erikson,generativity can take the form of

A) fostering the development of the young.
B) decreased concern for the well-being of others.
C) a maintenance of a youthful lifestyle.
D) indulging oneself in long-delayed pleasures.

According to Erikson, generativity involves a desire to guide and aid the next generation, whether through parenting, mentoring, or societal contributions. This entails fostering the development of the young and making efforts to positively impact future generations, rather than focusing solely on one's own pleasure or desires. Therefore, option A is the correct choice. Option B, decreased concern for the well-being of others, would be a sign of stagnation rather than generativity. Option C, maintenance of a youthful lifestyle, is not necessarily indicative of generativity although it may be a personal choice. Likewise, indulging oneself in long-delayed pleasures (Option D) is not necessarily a sign of generativity.
