Final answer:

Step-by-step explanation:
The term that best describes the individual's stage of identity formation is Identity Foreclosure. Identity foreclosure occurs when an individual adopts an identity without actively exploring other options or considering different possibilities. In this case, the adolescent has been labeled and identified as a 'basketball kid' without trying other activities or exploring other aspects of their identity.
This stage of identity formation is characterized by a commitment to an identity without going through the process of exploring different roles and possibilities. The individual may feel a sense of certainty and security in their chosen identity, but they may also experience limitations in their personal growth and development.
This stage is different from Identity Diffusion, where an individual has not yet explored or committed to an identity, and Identity Moratorium, where an individual is actively exploring different options and possibilities before committing to an identity.
