Answer:
The correct answer is - stomach.
Explanation:
The stomach is the only part of the digestive tract among the duodenum, large intestine, stomach, and esophagus that has three layers of smooth muscle.
The duodenum, large intestine, and esophagus simple columnar epithelium, and others have two -layers of smooth muscles and have simple columnar epithelium. This suggests that the mucosa is the section of the stomach in the digestive tract

Answer: A,C,D
Explanation:
Element in the same group shared similar chemical behaviour and resemble each other because of the same number of valency electron they have. Example group one element have a valence electron of one.
Because of the same Valency electron they react in a similar way.
Example Group 1 have one valence electron and therefore Ionize readily to form positive electron this occur when they donate their valence electron leading to the formation of electrovalent compounds this is applicable for all group one element. Hence,
Elements in the same group have similar properties and react the same
Also, because element in the same group share the same property in chemical behaviour they are said to belong to one family.
Element in the same group do not have the same energy level because their electron tends to increases down the group and therefore energy level increases and not constant for all elements.
