Final Answer :
A
Explanation :
The correct order of the segments of the small intestine is duodenum, jejunum, ileum. This is the order in which the food passes through them during the digestive process. The duodenum is the first segment of the small intestine where most of the chemical digestion takes place. It is followed by the jejunum, which is the site of nutrient absorption, and then the ileum, where absorption of vitamin B12 and bile salts occurs.
