Answer:
The category which leads to the most psychological health is d) identity achievement.
Step-by-step explanation:
Psychologist James Marcia refined Erik Erikson's theory of psychosocial development, and focused on the development of teenagers. According to Marcia, adolescents go through four different stages of identity: diffusion, foreclosure, moratorium and achievement.
While diffusion is the least mature status, identity achievement is the one that leads to the most psychological health. It indicates that the individual, after exploring and experimenting, has chosen a coherent identity, a value, or a role and committed to it. However, this status is often not achieved during adolescence.
