Final answer:
Rose is in the stage of late adulthood, aligning with Erikson's stage of integrity versus despair, reflecting life with pride indicating a sense of integrity.
Step-by-step explanation:
Rose is in Erikson's stage of late adulthood. This stage corresponds to his concept of integrity versus despair, during which individuals reflect on their lives. A sense of satisfaction, pride in accomplishments, and few regrets indicate the achievement of integrity. On the other hand, feelings of bitterness and despair might arise when one is unsuccessful in navigating this stage. According to Erikson, successfully achieving a sense of integrity at this stage enables individuals to look back on their lives with a sense of fulfillment.
