According to Erik Erikson's theory, which task pertains to middle adulthood?

In Erik Erikson's theory of psychosocial development, the stage associated with middle adulthood is characterized by the challenge of generativity versus stagnation. This stage typically occurs from approximately ages 40 to 65 and focuses on the individual's desire to contribute to society and support the next generation.

The correct choice regarding this stage is the willingness to care for others, as it encapsulates the essence of generativity. Individuals in this stage seek to create or nurture things that will outlast them, which often manifests through parenting, mentoring, and participating in community activities. This motivation to care for others is pivotal in fostering a sense of fulfillment and purpose in adulthood.

The other options, while related to decision-making and guidance, do not specifically capture the broader societal and generative aspects that Erikson emphasized. Rather than focusing solely on marriage, career decisions, or parenting roles, the primary task in middle adulthood is about fostering growth and caring for others in a more expansive sense.
