The correct answer is A.

Bulimia nervosa is associated with bingeing and purging which means that people with this eating disorder will eat and eat and eat until they feel sick and then purge what they have eaten by vomiting up their food. In this way they are not actually allowing any of the food they have eaten to digest in their stomach and put on any weight.
