Answer:
Even without the options, it is possible to answer this question. Marcia would place Billy in a state of identity diffusion.
Step-by-step explanation:
Psychologist James Marcia focused on the development of adolescents, refining Erik Erikson's theory of psychosocial development. According to Marcia, adolescents go through four stages: diffusion, foreclosure, moratorium, and achievement. Identity diffusion is the state where the person does not have a social identity yet. The adolescent going through this state is not actively searching for an identity, not experimenting. This person is not, however, going through an identity crisis. They haven't simply begun searching for what can help them define themselves. That is why answering "I have not really thought about it" as well as saying they do not know something, just like Billy did, is quite common.
