Answer 1

The correct option is D Mastication

Digestion includes breaking down of food into smaller components so that they can be assimilated by the body. Salivation is process of production of saliva from the salivary glands in the mouth. Once the food enters the mouth, mechanical grinding of the food takes place with help of teeth. This process of reduction of the food morsel into bolus by chewing is called mastication. Mastication increases the surface area of the food hence,it helps in breaking down of food by enzymes.

So, the correct answer is Option D.
