Answer:
d. integrity vs. despair.
Step-by-step explanation:
Erikson's stages of psychological development are the eight stages of development during the lifespan of an individual. Instead of just focusing on child development theory, his contribution covered entire lifetime.
The eighth stage of development theory is called integrity vs despair which starts around the age of 65 till the end. In this stage, an individual looks back at his life and feels a sense of accomplishment or regret. If he feels pride looking back his life he would develop into a more mature personality, which is a sign of integrity but if regrets about his life, it will lead him to despair.
