Choice B rationale:

Normal or slightly above normal body weight is a characteristic of anorexia nervosa. Anorexia nervosa is an eating disorder characterized by a distorted body image and an intense fear of gaining weight, leading to self-imposed starvation and significant weight loss. Despite being underweight or emaciated, individuals with anorexia nervosa often perceive themselves as overweight or obese, which is a key feature of the disorder.

Choice A rationale:

Recurrent episodes of binge eating are characteristic of bulimia nervosa, not anorexia nervosa. In bulimia nervosa, individuals engage in episodes of binge eating followed by behaviors to compensate for the overeating, such as vomiting, laxative use, or excessive exercise.

Choice C rationale:

Lack of interest in eating or food is not a characteristic of anorexia nervosa. This symptom aligns more closely with avoidant/restrictive food intake disorder (ARFID), where individuals have a lack of interest in eating due to sensory sensitivities or other aversive experiences related to food.

Choice D rationale:

Repeated regurgitation of food is a characteristic of rumination disorder, which is a separate eating disorder and is not a defining feature of anorexia nervosa.
