Solution

The correct option is B Duodenum
  • The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine and is where much of the digestion and absorption of food takes place. 
  • The small intestine is divided into three parts such as duodenum, jejunum, and ileum. 
  1. The duodenum is a first part of the small intestine continuous with the stomach and shaped like a "C". 
  2. The jejunum is the midsection of the small intestine, connecting the duodenum to the ileum. 
  3. The ileum is the final section of the small intestine. 
Thus, option A is correct.
