Step-by-step explanation:
Kevin demonstrates characteristics of identity diffusion. Identity diffusion is a state where individuals have not yet explored their sense of self and have not made any solid commitments to their future. This is shown by Kevin's lack of planning, ambivalence towards school, and his preference for hanging out with friends instead of contemplating his future. Kevin is not actively seeking answers to questions about his identity or future, which aligns with the characteristics of identity diffusion.
