Hi Dfalero, The argument introduces and then rejects a position that therapy is a form of coercion. The author rejects this on the grounds that the goal of therapy is to increase choices, but coercion removes choices. This is flawed because just because the goal is to increase choices, the methodology might involve temporarily narrowing choices. This closely resembles C.
A is incorrect as the author does not ever redefine a position. The position they argues against remains that therapy is coercion. The shift comes in switching from discussion of the methods of therapy to its goals.
