She insists that she is not well and requests her parents repeatedly to admit her to a hospital. Upon examining Laura, Dr. Harris, who was treating her, told her parents that her behavior seemed to be maintained by an inner need to play a "sick" role. In this instance, which of the following disorders is Laura most likely to be diagnosed with?

b. Munchausen syndrome
c. Anorexia nervosa
d. Avoidant restrictive food intake disorder
