Answer:
C) dense microvilli
Explanation:
The modification of simple columnar epithelium that allows for efficient absorption along the digestive tract is Dense microvilli.
microvilli increase the surface area of the simple columnar cells allowing more space and opportunities for nutrients to be absorbed from the lumen of the intestine into the bloodstream.
Microvilli are microscopic cellular membrane protrusions that increase the surface area for diffusion and minimize any increase in volume. They are involved in a wide variety of functions, which include absorption, secretion, cellular adhesion, and mechanotransduction.
