Which of the following eating disorders often begins in late adolescence or early adulthood after a series of various unsuccessful weight reduction diets?

Correct option is D

Sol. Anorexia nervosa is a psychological eating disorder that often begins in late adolescence or early adulthood, commonly triggered by body image issues and repeated failed dieting. It involves extreme food restriction and a distorted perception of body weight and shape.
Explanation of each option: • (a) Anorexia – This is a short term for anorexia nervosa but isn’t the full clinical name. Also, "anorexia" alone can mean loss of appetite, not necessarily the disorder. • (b) Bulimia – Involves cycles of binge eating followed by purging (vomiting, laxatives), not mainly weight reduction dieting triggers. • (c) Anorexia bulimia – Not a medically recognized term; it wrongly combines two distinct disorders. • (d) Anorexia nervosa – Correct. It typically arises in young adults obsessed with weight control, leading to severe food restriction.
