Answer:
Option C, Small intestine; absorbs fats and fatty acids
Explanation:
We will look at the functions of all the given structure
a) Cardiac sphincter - Just like a cardiac system it prevents the back movement of food from stomach to esophagus.
b) Stomach - digestive enzymes and acid act on the food to digest it.
c) Small intestine - its main function is to absorb nutrients and minerals from food. Thus, absorption of fats and fatty acids is the right function of small intestine
d) Colon - it forms stool after the re-absorption of left out minerals and fluid in the digested food passed on by the small intestine.
Thus, option C, is correct.
