Answer 2

Answer:

The correct answer to this question is option (a) oesophagus.

Explanation:

The process of digestion of food starts with the food entering the mouth, where the enzymes present in saliva breakdown the food up to some extent.

Oesophagus doesn't produce any sort of enzymes on its own but the saliva from the mouth is carried from mouth to the oesophagus to the stomach. While on its way down the stomach, the salivary enzymes keep on working on the food. The only work oesophagus does is move the food to the stomach with the help of peristalsis.
