_ The Correct ans is EEE.
The most common cause of such diffuse malabsorption, celiac disease, has a characteristic biopsy pattern with short or absent villi. Confirmation of the disease requires response to a gluten-free diet.

The osmotic gap is a characteristic of osmotic diarrhea in particular ( Choice A ).

Stool fat, D-xylose testing, and Schilling tests help establish the diagnosis of malabsorption, but not the etiology ( Choices B,C,D ).
