What is NOT one of the factors that have been linked to the development of anorexia nervosa or bulimia nervosa in young women

A)  mothers who model unhealthy dieting behaviours for their daughters 
B)  parents who are negligent or uninvolved in their children's lives 
C)  a genetic vulnerability to eating disorders 
D)  the presence of rigid, all-or-none thinking and maladaptive beliefs

Negligent or uninvolved parents have been linked to various negative outcomes in children, but research has not consistently linked them to the development of eating disorders in young women. Factors such as societal pressures to adhere to unrealistic beauty standards, a culture that promotes dieting and thinness, and individual psychological factors have been more strongly linked to the development of anorexia nervosa or bulimia nervosa.
