The correct option is A False
In the mouth, food is mixed with saliva. Saliva contains salivary amylase. This enzyme acts on starch and converts it into maltose. Food from the mouth then passes through the oesophagus to reach the stomach. In the oesophagus, the action of salivary amylase continues but the oesophagus itself does not produce any additional digestive enzymes. It basically transfers the food bolus from the mouth to the stomach.
