D. Body image disturbance is a fundamental issue in anorexia nervosa.

A. While adolescents with anorexia may exhibit behaviors related to food restriction, excessive exercise, or other rituals, the core issue goes beyond simply adhering to appropriate behavior. Anorexia nervosa is driven by deep-seated fears, anxieties, and perceptions related to body image and weight.

B. Control is a central issue in anorexia nervosa. Adolescents often use strict control over food intake and exercise as a way to manage overwhelming feelings of anxiety, fear, and uncertainty. By controlling their food intake and weight, individuals with anorexia may seek to regain a sense of mastery and control over their lives amidst other stressors.
