Final answer:
Individuals in identity foreclosure, according to Marcia's research, are most likely to become authoritarian parents because they commit to identities without exploring and strongly adhere to set rules.
Step-by-step explanation:
Generalizing from Marcia's research on identity, the individual most likely to become an authoritarian parent is b. Identity foreclosure. This is because individuals in the identity foreclosure status have committed to an identity without exploring options. They are likely to adhere strictly to rules and expectations that have been set for them, often by their parents or authority figures, and this approach to life may extend into their parenting style. They may favor a structure where obedience and conformity are valued, which aligns with characteristics of authoritarian parenting. Marcia's four identity statuses—identity achievement, identity foreclosure, identity moratorium, and identity diffusion—reflect different processes individuals go through in developing their sense of self, with those in foreclosure having made commitments without exploring alternatives.
