Solution
The correct option is B Columnar epithelium Simple columnar epithelium is a single layer of tall cells that arranged like a pillar. The digestive tract - stomach, small intestine, and large intestine are lined with columnar epithelium because the small intestine is the part of the gastrointestinal tract between the stomach and the large intestine, and is where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food and columnar epithelium provides a large surface area for more absorption.
