Final answer:
The correct response to the student's question is C. Developmental Models, which are based on humanistic psychological theories that focus on individual growth and self-actualization.
Step-by-step explanation:
The models of supervision described in the question aim to identify and maximize growth needs, with an emphasis on the idea that we always have potential for growth to some extent. The correct answer is C. Developmental Models, which are based on theories by humanistic psychologists such as Abraham Maslow and Carl Rogers. They asserted that individuals strive toward self-actualization, emphasizing free will, self-determination, and the desire to become the best they can be. This is contrasted with other approaches such as the Social Role Model, which may focus on conforming to societal expectations, and Psychotherapy-Based Models, which derive from therapeutic techniques such as client-centered therapy. Developmental models incorporate the understanding that personal development involves processes of selection, optimization, and compensation throughout the life course.
