The increase in the incidence of eating disorders such as anorexia nervosa and bulimia nervosa has been referred to as a "collision between our culture and our physiology." The most accurate interpretation of this statement is that .a. people have become too dependent on media determinations of beauty.
b. media standards of beauty are increasingly unattainable for the average woman.
c. dieting has become a fad that has been taken to an extreme.
d. beauty is now being defined by different cultures in society than before.

b. media standards of beauty are increasingly unattainable for the average woman.

Explanation:

The media standard of beauty means beauty standards shown by actresses, models or other celebrities etc.

Our society now a days expect a woman to be beautiful and perfect as the actresses or models.

A continuous craving to be considered as beautiful has forced an average woman to adopt ways of losing weight and maintain a slim or skinny figure.

But this desire has lead them to certain serious mental disorder in which they either lose the desire to eat (anorexia nervosa)  or slip into depression after eating and switch to unhealthy practices of losing weight (bulimia nervosa).

Thus we can term that our culture and physiology collides with each other and takes a form of serious disorders like these.

the answer is trees if i'm not mistaken
