Explanation:

The digestive process begins with the mechanical and chemical breakdown of food. Chewing (mastication) in the mouth starts the mechanical breakdown, and saliva (with enzymes like amylase) starts chemical digestion. Option A is when food enters, but digestion starts with chewing. Option B is incorrect as digestion starts immediately. Option C is swallowing, which is after initial digestion in the mouth. So the correct answer is D as chewing initiates the digestive process.

Answer:

D. When you chew a bite of food
