Answer:a.Anorexia nervosa
Explanation:
Anorexia nervosa, which is commonly called anorexia is an eating disorder that makes a person have an extreme fear of gaining weight such that they start to extremely restrict their food intake and they have abnormal desire to be thin.
The person may be extremely thin but they see themselves as overweight, but in reality they are underweight. They will vomit , take laxatives and use any dieting method, even when they have lost a lot of weight they still can't see it.
They may also over exercise , lose weight but still feel overweight.
This is a life threatening disorder that is driven by emotional issues because a person usually feels like being thin is equal to being worthy.
Symptoms
A person starve themselves constantly and they have unrealistic weight loss goals. An abnormal fear of gaining weight even though the person may already be too thin.
I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)
but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
