Solution
The correct option is B Mouth
- Chemical digestion involves enzymes. In the mouth, chemical digestion is initiated when the food comes in contact with saliva, which is secreted by salivary glands.
- It contains salivary amylase which begins the digestive process by breaking down starch and converting it into maltose.
- Chemical digestion then further continues in stomach and then finally in the small intestine.
So, option A is the correct answer.
