According to Erik Erikson,an adult's failure to achieve generativity results in:

A) intermittent feelings of loneliness.
B) stagnation and personal impoverishment.
C) childlessness and depression.
D) difficulties in mate selection or friendship.

Erikson believed that generativity, or the desire to contribute to the next generation and leave a positive impact on the world, was a crucial developmental task for middle adulthood. Failure to achieve generativity would result in stagnation and a lack of personal growth, leading to feelings of emptiness and unfulfillment. None of the other options are specifically mentioned by Erikson as consequences of not achieving generativity.
