Answer 2

Option A is correct

Jejunum

Explanation :

• In humans and most higher animals, such as mammals, reptiles, and birds, the jejunum is the second section of the small intestine.
• Its lining is designed to allow tiny nutrition molecules processed by enzymes in the duodenum to be absorbed by enterocytes.
• The jejunum is located between the duodenum and the ileum, and it is thought to begin at the duodenojejunal flexure, which is where the suspensory muscle of the duodenum begins.
• There is no anatomical difference between the jejunum and the ileum.
• The small intestine in mature humans is generally 6–7 m (20–23 ft) long (after mortem), with the jejunum accounting for roughly two-fifths of that length (2.5 m (8.2 ft).
