Answer 1

The correct option is A Digestion of food

• Saliva is a thick, colourless and glistening liquid with about 98 percent water in our mouth. The saliva contains chemicals like mucus, salts, antibacterial substances, and enzymes that help in the digestion of food especially starch.
• The digestion of starch into sugar is done in the mouth because of an enzyme, salivary amylase that the saliva contains.
• Saliva also helps to make the food into a bolus structure. For the ease of transport into the stomach.

So, the correct answer is A.
