Solution

The correct option is A Mouth
Digestion starts in mouth and starch is the biomolecule whose digestion is first carried out by Ptyalin enzyme present in saliva.
No digestion occurs in oesophagus. It functions to transport semi solid bolus of food from mouth to stomach.
Intestine comes after stomach. Stomach is important for digestion of proteins.
