Anorexia nervosa is?

• A. A habit of overeating rapidly.
• B. A temporary fasting practice.
• C. A reluctance to exercise.
• D. Refusal to eat.

Answer: (D)

Anorexia nervosa is an eating disorder defined by persistent restriction of food intake, often driven by an intense fear of gaining weight and a distorted view of body size, leading to significantly low body weight. The description that describes refusal to eat best fits this pattern because it highlights the core behavior of restricting intake. The other options describe behaviors that are not defining features of the disorder: overeating rapidly points to binge eating tendencies, temporary fasting can occur in non-pathologic contexts, and reluctance to exercise is not the central problem—though some individuals may exercise excessively, the key issue here is the severe restriction of intake.
