Final answer:
A person exhibiting behaviors such as binge eating, food restriction, or purging at sub-clinical levels may be experiencing Eating Disorder Not Otherwise Specified (EDNOS).
Step-by-step explanation:
When a person engages in behaviors such as binge eating, food restriction, or purging, but not at the levels that would qualify as a major eating disorder, that person is said to be experiencing Eating Disorder Not Otherwise Specified (EDNOS). EDNOS is now more commonly referred to as Other Specified Feeding or Eating Disorder (OSFED) as per the DSM-5, which encompasses a diverse group of eating disorder symptoms that do not neatly fit into the diagnostic criteria for anorexia nervosa, bulimia nervosa, or binge eating disorder.
Misconceptions about body image and fear of weight gain may drive these individuals to adopt harmful eating habits. However, their symptoms are not frequent or severe enough to meet the full criteria for the more commonly known disorders.
The correct response to the question is: A. Eating Disorder Not Otherwise Specified (EDNOS).
